Thanks, those pantos are very cool and super aggressive IME. I lost a couple bartonis due to bloat a few weeks ago and in my opinion they're pretty delicate. For some reason the problems came after feeding them frozen food (bloodworms and brine shrimp). I did'nt think it would be a problem since that's part of all my other fish's diet. I now feed them very lightly flakes and anti-parasite medicated fish food to avoid problems. I don't see them eat, but they must be eating it.
