Have a peacock eel and a featherfin catfish. I have lots of caves for them, but would like to add driftwood instead, and more plants for a more natural look. Im just wondering, do either of these guys need caves abd territories? Or could the do fine with plant and DW cover? If i found big driftwood pieces would they be fine? I dont want the featherfin to get agressive and territorial with others, because he likes his cave. Heres what the tank looks like. 40 gallon planted community
