|Breeding||Spawns in pairs or groups, having more than one trio (2 females and one male) increases chances of spawning. Eggs deposited around the tank, on glass and plants. Perhaps prefers plants. Eggs are 1mm in size, female carries only one egg at a time in ventral pouch. One female can lay up to 100 eggs per spawning cycle. C. pygmaeus rarely eat their eggs. |
Fry will feed on micro organisms in the tank and on an open sponge filter if present. If hatched out of spawning tank microworms, vinegar eels, rotifers and small daphnia such as Cerio daphnia will be accepted.
