I love my plecos, I feed them all kinds of stuff. I've read and seen frozen vegetables like peas being used. I want to buy some frozen vegetables, because we don't eat things they would accept fresh every day (shame on us) , to maintain a healthy diet for a clown, a rubber lip, and a spotted sailfin (gibbiceps), all juvenile. Any good suggestions? I also heard fresh potato is good, should I blanch it or just stick it in raw in the veggie clip?
