I've seen it once with my red cap lethrinops except he didn't park her in a corner rather let her free swim throughout the tank and any fish that would get near her he would chase away, almost looked as if the female had her own secret service agent detail assigned to her
have to admit it was quite interesting to watch and lasted for about the first 3 or 4 days after they had spawned before he left her on her own and started courting the next female in the tank
I noticed what I think is unusual behavior in a pair of L. chisumulae. They had just spawned and the male seems to be protecting the female by keeping her in a corner and keeping all other fish away. She definitely is holding and he is not pressuring her into attempting to spawn again. Has anyone seen this type of behavior before?
