I used to have a 135 gallon tank and I have had a panther, miniatus, argus, damperia, vtail, blue and gold, marble shark, and a saddleback not all at the same time. I know the saddle eats alot like the blue and gold and the two of them grow faster. When the miniatus or the vtail would eat two shrimp or silversides and be full, the bue and gold and the saddleback would eat 6. The saddleback and the shark got along great except a few scuffle at feeding time.
My friend have a miniatus in his tank for like a week and then he put a panther, damperia, and a blue and god grouper in on Sunday. The miniatus kept trying to fight the blue and gold.He doesnt have any rock works because he says he have had the rocks fall on precious fish and kill them.. And get this, he have a 55 gallon tank. I tried to tell him. I tried to give him my old 135 a while back but he says he doesnt have the space, so I guess he has a back up plan.
