this really sucks.. just last month my aro started getting fin rot in 55 gal. i was planning on putting him in 150 gal but his sickness held it up.. i got maracyn and maracyn 2 and the rot withered away.. i threw him in the 150 and he looked beautiful. i recently(recently) had to remove overflow because of a leak, so i resealed overflow and let dry for a day.. i looked in tank today and noticed that his gills were curling back a little... SO FRUSTRaTED!!! any aro doctors out there.!!?
