is there any conspecific aggression between the juvenile tilapias?
I moved them from the quarantine tank into my 75 gallon 'swamp' where I keep a few fish that just don't fit in any where else.
Conspecific aggression seems typical for juvenile african cichlids. The larger (male?) will chase the others away during feeding time but doesn't harass the fronts, labs, zebras or polypterus that live in the rock pile.
In the picture below you can see some damage to the dermis of the maxilla of one of the smaller pair.There was some lose skin but the wound healed very fast. I don't know if it resulted from some lip locking or not, as I was at work when it hapened.
In general the finnage and skin of these fish looks good, which would indicate that they don't scrap very much....yet.
