how to decorate aquarium




Watertanks containing only fishes is a dull watertanks and no ornament to a house. First thing that we have to think about is covering the bottom of the watertanks with sand or gravel in which the plants can be placed and where, eventually, they will root themselves.
Some people like to place a layer of leaves or peat moss beneath the sand. We should be careful to choose only well rotted oak or beech leaves as many others leaves contain substances which, although they may not harm the plants, are poisonous to the fishes. For common average aquarist, however, there is little need to bother with peat moss or leaves. Sand or gravel will be enough as the fishes, in the course of nature, will fertilize the plants.
For general purposes of covering the bottom and making a place for the plants there is nothing to beat the coarse gravel which can be obtained from any aquarium supply shop. For an extra amount, you could be little fancy with white quartz gravel which will look very pretty when the watertanks is newly set up. But unfortunately those white quartz gravel will become discolored in a short time, so that it will be difficult to tell it from ordinary and cheaper gravel.
Never use sea sand on the bottom of the aquarium. It’s too fine and is almost impossible to keep clean. Also it may contain lime which is not soluble in salt water, will make it too hard or alkaline for our fishes.
Shortly we will find that we need far more gravel than we supposed on looking at our watertanks. For a ten gallon watertanks, for instance we will require at least five pounds and more. First things to do after we buy gravel is to wash it. Pour the gravel into a bucket and fill the bucket up with water. Stir the gravel around thoroughly and then pour off the cloudy water. This action should be repeated several times until the water remains clear when you stir. The gravel is then ready for use.

Favourite thing about :
The most good thing about fighter fish ,i like about these fishes is that they are extremely beautiful and also they can survive in water with very low oxygen content.They have labyrinth organ so they have special capability to take oxygen directly from air above the water.So they can do well in small tanks and also with less oxygen supply.Due to this reason i have seen many aquarium dealer who put them in beaker who's size is about few inches which i really hate.

how to breed fighting fish

 Siamese fighting fish breeding is quite enjoyable task.However risk factors rises because of their aggressive nature towards same species. This fish can successfully breed in less amount of water, i would prefer 10 gallons minimum.During spawning their may be very high chances that your fish may get few injuries and you are ready to take the risk.They give about 500 eggs at a time so you should have facilities to arrange home and food for them.Don't add any stones or gravels to the bottom of tank.
Steps:
1.Arrange 10 gallons tank, with clear water , add sponge filter ,water heater.Set the temperature of tank 80-82 degrees.The most important thing is that you should be able to partition the tank with glass so that they can see each other and you should put lots of hiding places in tanks so that female can hide.
2.Arrange for 1 male and 1 female ensure that they are nearly of same size and they are in healthy condition.The age of them should be around 1 year.
3.Feed them high quality food,especially live food or you can opt for frozen bloodworm.
4.Put lots of live plants as they will provide hiding place for females and food for fries however fake plants will also work as hiding place.
5.Add the tank divider in the tank you can give more space to male.
6.After 3-4 days turn of the sponge filter and introduce the male in one section and female in another after 1 hour when male is added.
7.Turn off the sponge filter now. remember the male and females should not be able to have direct contact.
8.Now observe them, if they are interested in each other the male will develop bubble nest and should be flaring his fin around the female and female will angle her head down submissively and develop vertical bars on body.Then if they are extremely aggressive and trying to attack through glass, then remove them try this after few days.Other wise this is right time to release female(probably 1 day after introduction)
9.Now, they will chase each other, some aggression will normally observed.So you should have provided hiding places.Chasing can be violent they may nip each other fins and tails.If spawning doesn't occur in 48 hours then try after few days or you can try with different pair.
10.If they are interested i have told the sign before, don't feed them. When both of them are ready to breed then female will move under the nest and male will wrap his body around the female.They will embrace each other.
11.This help female in squeezing the eggs.During this time females doesn't show movements and becomes like zombie during the falling of eggs.While male starts putting the eggs in nest.This process is repeated several time .When this process stops remove the female from the tank remember don't disturb nest and male.
12.Treat the tank with Maroxy as it prevents fungus attack on eggs and help in recovery of fishes.
13.After 3-4 days the babies will start coming out from the nest.Turn on the sponge filter but at very low power (slow rate).Take care that babies are not get squeezed by it or any other filter.Remove the male now.

14.Now feed the fries with microworm after 8 hrs , don't overfeed them.Use eyedropper and put 2-3 drops only.You can find that babies are feeding on worms on close observation.
15.If you find microworm on the bottom of tank till the nest feeding time ,then skip the next feed.
16.Microworm older then 1 day should be removed with siphon carefully , don't suck any fry.
Repeat this process for 1 month.
17.After 1 month you can feed them some larger food like baby brine shrimps,frozen daphnia
little pieces of frozen bloodworm.
18.Gradually increase the amount of food.If death rate of fries is very high then check for pH and temperature etc.
19.After 5-6 week starts feeding them frozen dried flake and pellets.Now starts moving the males into separate container at the age of 7-8 weeks.However females can be kept together at some extend.
20.After 8 weeks you have to find new home for new generation,you can put them in pond or sell to pet dealer and earn some credits.You can gift them to your friends and family members.

angelfish breeding at home

For eminent raising you tell a reasonable arrange of falls seek.But before spawning it is rattling serious to terminate which one is antheral and which one is person.Until you seem them at the indication of spawning time watching individual birthing eggs and male fertilizing them and noticing their filler of papilla .Mortal's papilla is smallish while females papilla is beamy and stark.
So you need a pair of angel fish.
The prizewinning way to do it is get 8-10 physicist supporter seek and put them in 50 gallon vessel.The degree of containerful should be nearly 18 inches.When they get their filler of about 1.5-2 inches in length or at a age of 1 year, they module couple off themselves,and they present superior a territory and move other seek way.This is a region that unite is chainlike now run this couple to identify containerful.From a assemble of 10 you may get 3-4 pairs.

If food is left even after 5 minute then remove it.If female become aggressive and having bulging belly then she may be carrying eggs.To angel fish grooming each other is also a sign that they are going to spawn .Before spawning they show their papilla .Papilla is a Small pink organ present near their anal fin.They also lock their lips and twist around.When they are ready they choose a site to lay eggs which may be any flat surface or broad leaves of aquarium plants and they will star it cleaning.You can put spawning slate so they lay eggs.

Now the female will deposit eggs on the slate or at any other place such as plant's leaves.The male angelfish will fertilize them by touching eggs with its papilla.If their is no male present then other female may do the same but this will not result is fertilization and soon eggs will turn white.
After fertilization

If their are additional fishes also in the unvaried cell then they may eat the eggs during the nighttime.However the pair of angelfish tries to protect their eggs.So you moldiness supersede additional fishes from the tank where percoidean unite is present or you should bang put brace in asunder tank before spawning.Sometimes it is also observed that parents may eat their foodstuff and sometimes they protect.So you moldiness purchase a observe on that.You can put a spawning list,or helping of stone,or rid tile.This give serve to relocation the eggs to distinct.Now suggest that pot tally h2o and eggs from cell to another cell.

After about 48 hrs eggs will start showing fry tails.On third day you can see their yolk sacks.These will be still attached to the slate or leaf.If the parents are in still in the same tank they may start moving small fry.After a week you will find them swimming freely now they will need food.

lyretail molly fish breeding


You must be knowing that all molly fishes are same species so you can breed any one of them with any other Molly fish. Breeding is very simple task.You need one male and few females with good water conditions.The number of females should be more then the males because males like to chase females ,this makes females more stressed.She can even give birth to several batches of babies over a year even in absence of males because of their sperm holding capacity.Before hand you should also arrange home for new babies else avoid their breeding.
If females are stressed then they may give birth to unhealthy babies or immature babies.So try to put lots of hiding places for females.
The gestation period of females is of about 30 -40 days.Females will start becoming more rounder as the time pass.When the female will about to give birth her stomach shape will be like \___/ .Then females will give birth to fries.Remember they are live bearers .They will give birth about 30-40 fries at a time in time of about 1-2 hrs .In my case they give to birth to 30 babies in 1 go and on the next day she again give birth to 10 babies.
Remember to shift the mother or any other fish away from babies otherwise they will eat the babies.However mother will not react to babies while she is delivering the babies but after process is complete then she may try to eat them.
You can use breeding nest if you are not having any separate tank for babies development Breeding nest is made op of separate net fitted on plastic structure and you can attach it in main aquarium.You can put babies in it till they grow enough that is about for 1 month.
Remove gravels from the tank else fries will be crushed under them and use sponge filter so fry may no got suck in any other filter.Feed the babies crushed flake food and try to avoid disturbance to them.Then 25 % of water in a week.Don't over feed them.If you are having live plants in tank of babies it will benefit them.

Provide them lots of hiding places and live plants to decrease stress on them.Try to put 2 -3 females per male because male may chase female for breeding and females will get exhausted and may die.Change about 25 % of water once in a week.Do not mix any large fish other wise guppy will serve as food for them and also don't put them with any fin nipping fish.
Breeding: live bearers like molly fish

Food:Omnivorous may eat almost anything
Temperature:23- 30 degree Celsius
Lifespan:3-5 years

guppy fish breeding at home

Since guppy fish are live bearers these are relatively easy to breed as compared to egg layers fishes.For breeding you will need a healthy pair of guppy fishes. If you are using one male per female then there may be chances that male will stress out females for breeding attempt.So in this case provide lots of hiding places for female. Or you can put 3 females per male.Then in second case you may get 3 pregnant guppies.When males and females are present together then they will surely breed.Sometimes it is observed that females are already pregnant when you buy them from aquarium shop.You can tell it by looking at belly if you find dark spot known as gravid spot then female guppy is already pregnant.
The tank should be 10 gallons or more.Set the temperature to 77 to 79 degrees Fahrenheit .Provide them protein rich food , live food will be the best choice but other will also do fairly well.Change the 25 % of water per week to encourage breeding.The gestation period of female is about one month then she will release 10-40 babies in 1-2 hrs.The female guppy fish are capable of giving birth for many months even in absence of males.When female is about to give birth then her belly will become thick and you can see gravid spot.Also you can notice some change in behaviour that is she may eat less food or move slowly.
If you are having only one main tank.
If you are having only one main tank .Then there may be high chances that the new born babies will get eaten by the mother or other fishes.However mother is not interested in eating till she give birth to all babies it may take about 1 hour.So you have further choices.
If you are having fairly large aquarium then you can provide lots of hiding places by adding fake or live plants.You can add java moss or java fern.Add floating type plants and remember the other fish should not be able to see or access the babies.Remove the gravels before hand because fry may die if gravels fall on them.You can use spawning mop to provide hide out and caves made up of rock and marble chips.
If you want to go for another option there is 2 other equipment available in market known as breeding box and breeding net.Breeding box is plastic chamber in which you can put the pregnant female .While she give birth the babies enter to another chamber present at the bottom of it through the holes while mother guppy can not.Here you have to put the female while she is giving the birth or before hand.Here you need not to be present .The other option is breeding net.It is box made up of net and it can be attached to the Wall of aquarium.You can put the females in it but you need to be present because here babies will be present with the mother.When she complete giving birth then move her to main tank.The breeding net will provide protection from adult fishes.The breeding net should be present where proper temperature and water circulation is maintained.
If you are having separate tank.
Then put the breeding pair in separate tank .When female give birth to babies after that remove back the female to main aquarium.The size of this separate tank must be 5 gallon or more.Remember not to add gravels and use sponge filter .If you are using any other powerful pump then they may get sucked up in pump or filter.So decrease their power or tight their ends.So they may not get sucked up.If you have moved the fry from main tank then add water of main tank and try to maintain same parameter as of main tank .Do water changes 50 per week is enough or 25% per 3-4 day.
Feeding and Care of Fry:
Feed the fry brine shrimps , newly hatched daphnia or you can give them hard boiled egg's yolk the yellow portion of egg.Form a thick paste of egg yolk then add very tiny amount of it.Try not to add it in extra amount , if possible remove the remaining food from aquarium other wise it may spoil.But doing so don't harm the babies.Or you cab crush the flake food then form a paste then give to guppy fry.Give them 4-5 times in a day but in very small amount.As i have told you earlier cover any suction device if present.Switch on the light for 14 to 16 hours only.Set the temperature to 80 degrees Fahrenheit.

The above one is female neon tetra while below one is male.

neon tetra fish breeding

Neon tetra breeding is quite complicated.They can be breed at nine month of age.It is hard job for especially for beginners.However it is possible.This is one of the reason why neon tetra are imported in U.S.A.However you can school of neon tetras can produce hundreds of eggs in month.The female gets ready to spawn in every 2 weeks.However many eggs fail to develop and eggs or fry get eaten by other members or parents.But you can get success if you do it correctly.
You will need separate breeding tank:
For breeding neon tetra you will need separate breeding tank.So that as soon as eggs will get fertilized you should be able to remove parents as quickly as possible.Get 10 gallon tank for breeding.The tank should not contain any gravel or sand. You can use rock to cover the bottom at least of 2-3 inches.You should have lid to cover the aquarium else neon tetra may jump during spawning.Remove any other fish or snail else they will eat the eggs .It advised to sterilise the items you add in the tank by boiling them to 20 minutes..Add fine textured aquatic plant.Put rainwater if possible or pour aged water.Run filter in aged water to built beneficial bacteria colonies.Put sponge filter at very slow rate with closed tight ends..Add the male and female tetras in evening.You can add breeding mop to tank.Some aquarist let the level of nitrogen rise and then change 50 % of water to simulate rain.As this happens in Amazon
It is observed that neon tetras spawn in morning time.Use a dim light or cover the aquarium to exclude extra light.Eggs are light sensitive and may get damaged in light. Set the heater to 70 to 72 degrees Fahrenheit.Feed them live food half of the time to induce spawning you can give them mosquito larvae or worms or brine shrimps.

Observe the spawning behaviour:
The male neon tetra will court the female by swimming around her in square pattern using short jerky movements by periods of motion less.The reduced girth of female and the decrease in interest level of both in each other will show you that the spawning is completed .You can see eggs if you look closely.After it remove the parents from the tank.They may give 40- 50 eggs in captivity.But not all eggs will turn into fry. The eggs are will hatch in 24 to 30 hrs.In 3-4 days fry will become free swimmers .

FEEDING THE FRY
Neon tetra eggs are very small and you can feed them infusoria . Infusoria will serve the need however you can give them rotifers and egg yolk for 1 - 4 weeks.After hatching 2 weeks later , change the 20% of water every other day.After one month they will star displaying colors.
