I have 1 common pleco and 2 Peppered cory's that have become Top feeders When i put the bloodworms in i usually walk away but today i was watching my 55 gallon with my Jack dempsey and newly aquaired Texas Cichlid, and i seen the pleco and cory's swim up the glass and once they reached the top theyd drift off the glass turn upside down and star eating the bloodworms, i put in Shrimp pellet's which they also eat. Has anyone else had any Bottom feeder do this?
