Breeding tank size: ten gallons
Number of Ottos : 3 1F 2M
Tank temperature: 25 c
Conditioning: to condition Ottos you will need a tank which has algae . Supplement their diet with blanched spinach or zucchini. Driftwood carries algae and is therefore a good decor for a breeding setup. They are herbivorous but I have been able to feed mine frozen bloodworms. The female will develop a rounder stomach due to being filled with eggs, whereas the males will remain streamlined.
Spawning is triggered by water changes using water that is a few degrees cooler than that temperature of the water in the tank. Like cory catfish the Ottos form a T shape. Not much more is known on breeding because it is accidental .
