I'm getting ready to start stocking my 150. The plan right now is a pair of gold severums, an oscar, and maybe some t-bars or managuense cichlids. I'm looking for some catfish that will hold their own in this tank. the only thing that comes to mind is a few pictus cats. What other options do I have in this tank for bottom-level fish? I'm not really interested in plecos, mostly catfish.
