My 150 gal has one jag, one carpintis, and one stalbergi. I am always looking for more fish and would like to add someting to this tank. Any suggestions? It doesn have to be new world, but I would prefer it. If it matters, Iam partial to the stalsbergi. On a side note, is there a common name for the stalsbergi? I was calling it a GT, but read online itsnot really a GT.
