I wouldn't mind venturing away from cichlids and into some larger oddball species which has lead me to knifefish. I have a 72x30x25 (LxWxH) with a 75g sump, stock is 4 clown loaches, 3 silver dollars, 2 severum, 2 hoplarchus psittacus, crenicichla bellycrawler, and a paratilapia polleni. The loaches and psittacus are quite small, almost too small for the belly crawler and polleni, so I have some time to wait while they grow out but if I wanted to go this route how big would the loaches need to be before introducing either of these knifefish? I'm open to suggestions outside of these species and knifefish as well.
Thanks
