2016/5/4 10:31:15

In this article we describe three freshwater fish tank fish in detail with information about their behavior, feeding requirements, tank and water parameters, what they look like and how to breed them.

Madagascar Rainbow Fish - Bedotia geayi (Family: Atherinidae)

Behavior: The Madagascar rainbow, also know as the Madagascar minnow, is happy in a community tank but prefers to be in a small shoal of its own kind.

It is an active swimmer. It is a hardy and peaceful fish that tends to dwell in the top half of the aquarium and has become very popular.

Water and tank conditions: A higher than normal temperature range of 25 to 28 degrees Centigrade is ideal.

Features and colors: A somewhat peculiar aspect of the Bedotia genus is the fact that the fish have two dorsal fins with the second one being much longer. It has a horizontal dark line running form its eye to the caudal peduncal. The main body color is olive green. It can reach lengths of about 8 cms.

Its vertical fins have dark borders and are yellow. The male is more darkly colored than the female and its caudal fin is colored red.

Feeding: It is not a fussy eater and will eat a wide range of food but it won't leave the top half of the tank to get it!

Breeding Conditions: Pretty easy to breed you will need a well planted tank with hard water at a temperature of 26 degrees centigrade. It will take several days for spawning to take place and eggs are attached each day by threads to the plants.

Normally the eggs will not be eaten by the parents. Eggs hatch after about a week and you then have a range of fry developed to different maturity due to the extended spawning period. They can be fed freshly hatched brine shrimp and fine dried food.

Merry Widow - Phallichthys amates (Family: Poeciliidae)

Behavior: This freshwater fish tank fish is ideal for the community environment. It is very active, sturdy and well-behaved.

Water and Tank Conditions: An average planted aquarium with a water temperature range of between 21 and 25 degrees centigrade will be fine.

Features and Colors: An unusual feature is the presence of a gonopodium (which is seen in the Family Poeciliidae) in the male. In effect it is a modified anal fin that is rod like and extends under its body and is brought into action during mating, with its hooked end attaching to the female.

The adult male can grow to about 3 cms but the female can be twice the size.The main color is olive green and the male has dark bars on its flanks and blue gills. The fish also has a splendid dorsal fin with black bordering but the female lacks this element.

Feeding: The merry widow prefers vegetable matter and green algae and will accept dried foods.

Breeding Conditions: Although this fish will breed readily it is prone to eating its young! You do not need a separate breeding tank but use a breeding trap and you should be alright. As the fish is viviparous it will give birth to live fry. Several broods may result in up to 100 fry but not that many will survive.

Penguin - Thayeria boehlkei (Family: Characidae)

Behavior: The reason its is called the penguin is because of its coloring and when it is still, its tails hangs down and it appears to look like a tiny penguin. It is also known as the Hockey-stick tetra. It is a bit shy on its own so you may find it hiding in the plants.

Better if it is in a small shoal. It is a lively swimmer, also peaceful and sturdy so will be an ideal freshwater fish tank fish for a community. You will need a cover for your aquarium as it is a good leaper.

Water and Tank Conditions: As an active swimmer you need to ensure there is plenty of swimming area and there must be some densely planted areas. The water temperature should be about 22 to 26 degrees centigrade.

Features and Colors: They can grow up to 10 cms. The tail is forked and the lower part is longer.The main body color is silver changing into olive green on its back. A black strip runs along the sides of the fish.

Feeding: Will eat anything really. Not fussy.

Breeding Conditions: A breeding tank with tall plants and water at 29 degrees centigrade should be employed. As in a lot of cases using the strategies of separating and conditioning the pair to be mated should be used.

Remove the fish from the breeding tank after spawning. Fry will appear from the eggs in three to four days and can be fed on micro live foods such as green water (suspended algae).

So there we have it. Three more freshwater fish tank fish suitable for a community environment for you to choose from.
