Dear Dr. Scharpfenfisch:

My crappies have some kind of bacterial or fungal infection that seems to be
slowly eating away at their caudal fins. I have no idea what it could be,
what with being fairly clueless and all. My best guess was to treat with
Paragon, and to throw in some extra tetracycline that I found way in the
back of the fish cabinet. The infection doesn't seem to be getting any
worse, but then again doesn't seem to be getting any better.

I've been treating for about six days now and I dose with the last
tetracycline tablet tomorrow. Please tell me what to do, so I can avoid
going out to buy more tetracycline on my day off.

Signed,

Troubled in Mollyville
