I have a 75 gallon driftwood dwarf sag kinda set up with 4 clown loaches, a green terror and an african featherfin catfish. My green terror is about to die of old age and am curious what I should get after he dies. I have a C-360 and Emperor 300 on the tank. Any suggestions would be great. Either a few of something like a family or a couple cichlids to one main showpiece. I just need ideas thanks.
