You don't move them WHEN they grow, you move them so they CAN grow.
Ok, maybe mine was a super rare case or something, never once did I see them fight, they cuddled together at night, and played around all day, five years, five inches, according to all this, they are bad, but I mean, I did it very successfully, I don't know what you want to do, good luck
Ok, I found out from the previous owner(my uncle) that they were already four years old when he gave them to me, but he did say that they were from the same litter and they never got separated, maybe that has something to do with it?
I had plants in one corner of the tank, took them out and the bala's were happy and swimming around. i feed them shrimp pellets and they seemed to be fine. yes i will move them very soon. they cichlids are acei, yellow labs and another kind i forgot its name.
