All those sound like great ideas. If u can find some try some striped bass or small mouth bass. Smb really remind me of coral rock cod groupers.Thanks man, I'm glad I bought them. They're 5-5.5 inches, I don't want to get sds because they would destroy the plants. I was thinking a juruense cat, some azuls or some wc severums or maybe some panda uaru. I do like the fire eel idea though
