We had 6 Panda Corys in our 48 gallon tank. Today we found one had died. While 4 of the others look fine, one seems to have about half of its tail missing. I am not sure the cause of it. Now, we've suddenly just noticed that about 3 of our Pandas have very small portions of there "top" fin missing. Can anyone assist by telling us what might be wrong and what we should do (if anything)?

We have a community tank: 5 glowlight tetras, 5 african lampeyes, 12 cardinal tetras, 2 platies, 1 guppy, 1 albino bushy pleco, 3 cherry shrimp and 3 japonica shrimp. Maybe the guppy is the culprit? I doubt many of the others could be...

The panda kind of looks like it may have been attacked and not something like finrot on its own. A couple of the others have very small amounts of fin removed too.
