This summer I am planning a 90+ gal setup. I plan to have a school of fresh water barracuda. They are top swimmers and are very wimpy fish, easily bullied by others. I am trying find some catfish that might do well in this setup. I would like something that gets around 6" but not much more than 8". I would also like some thing that looks like a catfish. I would like to have atleast 3 or more of them, whatever I end up choosing. Any ideas or suggestions? Thanks
