I bought an awesome Watermelon/Royal Pleco from our last auction and has cleaned up the tank real well. I usually drop in a few pellets or waffers late at night so my peacocks don't eat everything, not knowing if he's getting enough food. I know Greg M. says he loves zuchini but it floats, so I tried carrot pieces which sinks. Are carrots ok for plecos? Any other solutions? Thanks for your advise!
