I would worry about the rostratus in that mix. They are very peaceful and way more so than the others. They should be kept in bigger groups too. They will probably grow slower to boot. One of the slowest growing cichlids I have kept.
Hmmm....thanks for the heads up. I'll definitely keep my eye on them. I have no problem with pulling them out and giving them away if they become threatened.
Nobody seems to bother them right now, although they pick on each other occasionally. I guess a bigger group would help that huh?
