so i have 2 common BN's in a 55 with a trio of young jewel cichlids and 2 baby bichirs. The plecos were eating fine, but now that i've added the other fish, the plecos seem to only want to eat their meaty foods (shrimp pellets, blood worms, beafheart, hikari pellets). Now the larger of the 2 plecos' stomach has begun to swell and i'm worried about bloat. I've added a cucumber to distract him from their food and get him/her some vegtable matter. Besides reducing feedings, is there anything i can do to make sure my BN are healthy?
