OK, I keep these. Xystichromis phytophagus is the scientific name. They are pretty aggressive fish, not unmanageably so, but enough where decent numbers would be good. 1 male per 3 to 4 females is a great ratio, and I'd keep a group of no less than 6. The females can be just as aggressive as the males. I had a bunch of holding females, and ran out of room for holding mothers. I put a couple together...one ate her fry, beat up and killed another female.
These fish are herbivores, so best bet would be a spirulina based food source. Some protein is necessary, so go light on the meaty foods.
This fish will cross breed with other Victorians, as the females have a similar look to a lot of the other Victorians. Good mothers, if allowed to be in isolation with the fry. Spawns up to 25 aren't uncommon in small females. Very prolific.
Anything else?
