That Adonis pleco will eat just about everything.. you should try potatoes too..
My 7" adonis eats bloodworms, krill pellets, and shrimp pellets.. Occasionally a veggie wafer, but it was my understanding the adonis plecos are more of a meat eater..
HBH just put out a new 'soft & moist' sinking krill pellet, all my bottom dwellers absolutely love them..
