General information and care
An interesting barb because it can survive in unheated aquariums in the living room. Indeed they should not be kept in a warmer tropical fish tank with temperatures above 75F. They like a ph of 6.8 or neutral and the water should be slightly hard but they are not that fussy. There are some very nice colour morphs such as the neon rosy barb. They are a schooling fish and do better if there are at least 6 of them. They can fin nip when not kept in schools of 6 or more. They can grow up to 4 inch in the aquarium. They are hardy and tolerate less than perfect water conditions. And, they are an active fish. As such they make an ideal beginner’s fish. They eat flake food. But the occasional treat with live food is better for them.
They breed in shallow water. Males are redder and slimmer. Females are greeny gold and fatter. The males colour will intensify when they are in breeding condition while the females will fatten up with eggs. They are mature at 2.5 inches at about 5 months of age. They breed readily as long as they are healthy.
Preparation for breeding
Leave them in the community tank. Feed well with live food. Raise the temperature to 74F and watch their behaviour every morning. If the male is chasing the female at all then remove her to the breeding tank. Breeding tank should have water 6 inches deep. In the same night move the male to the breeding tank. Move the established sponge filters to the breeding tank. The breeding tank should have the same water as the main tank. Also, even if you don’t see the male chasing the female, if the female is very fat (egg laden) then remove her to the breeding tank but wait until the following evening before moving the male to join her. Many times the adults will spawn in the community aquarium. If this is observed, wait until they have finished then remove the egg laden plants with some of the water from the aquarium to a separate tank.
Breeding rosy barbs
Maintain the breeding tank at 74F. Watch the aquarium from dawn onwards. The ruddy male should be chasing the female all over the aquarium. When the female heads into the plants she releases eggs which the male fertilises. This process will carry on for a few hours until her eggs are exhausted. She may lay several hundred eggs. When the pair finish and start egg eating immediately remove the pair.
Raising the fry
Add some methylene blue to the water. Wait 2 days until the eggs hatch. Wait a further 3 days until the fry become free swimming then start feeding with infusoria, After a week start introducing baby brine shrimp and microworms. After a few weeks add some dry fish food to their diet.
