In my 180 gallon tank I have a 6" leopard sailfin pleco. I have many pieces of driftwood and i feed him green squash(zuchinni) every other day. Is there anything else i need to feed him or add to the tank to keep him healthy. In my 56 gallon tank I have a 1.5" gold nugget pleco and 2.5" royal pleco. I have one small piece of driftwood in the tank along with a fake driwftwood ceramic ornament. I feed them green squash(zuchinni) every other day. Is there anything else I need in the tank to keep them healthy. water parameters are fine so that's no worry.
