-The danios have been there from the start. The five male odessas have been there for three weeks. They are not new, just moved from my 10g. The 6 females have been there for two weeks. The 'sharks' have been there since friday(28?). All my fish are drip acclimated for 30mins before introduction.

-The only thing i've added are some terra-cotta pots last week. Everything else has been the same
What kind of food have you been feeding your fish, have you changed their diet recently?
-2 weeks ago i switched from omega one pellets to flakes, no problems. Occasionally frozen foods.
The problem fish isn't acting weird at all. Swimming with the school, eating ok. Gills look fine. The anal fin is definitely white and shredded. The tail, dorsal, pectoral, and pelvic fins seem to be unaffected as of yet. None of the others have white on them or seem to be acting odd, nor do they exhibit signs of nipping or fin rot. If anything seems to change in 8 hours when i wake up i'll note it. Thank you
