Ok I guess I'll keep my GSP alone in his own tank. I really hope he will get to his max size. How long does it take GSP's to get to 6"? In the future I might get a bigger tank, for now I'll keep him as a single fish with some ghost shrimp. Yeah I'm surprised that he hasn't eaten the ghost shrimp yet. But I think he is just too lazy to chase after them because they even try to get his food and hold on to it until it's in the gsp's mouth. That's why I thought it might be possible to have some BBG's with him, but I know this might change when he is full sized. When I got him he came with three panda cories (he was in a fresh water community tank), now the cories are in my sisters tank and my GSP is in the 34 brackish tank.
