I have 2 gulpers in a 55 with a rena xp1 and a tetra 60 hob. The water looks cloudy, they wont eat and the 1 is bloated. These are my favorite right now and this is really annoying. I just bought a 210 for an aro and stingrays and if this is going to continue I need to start rethinking a lot of things. I've been feeding them store shrimp and now they wont look at it. I try so hard and this is so frustrating considering my stupid 30 gal community tank is just fine. I hate losing fish and want to scream
