Anyone have any advice on round very red sores on the back and sides of CC and BG? These are much larger then the few pictures I can find here that survived the loss of legacy posts and pics. Maybe 1/2 inch across on BG, 3/4ths inch on the cats. Most infected fish have only one spot, but some have a couple. Its not on gills or lips and is so red at first I thought they were wounds from the heron and egret that enjoy my 1/2 acre buffet.
A week ago just a few cats had this, now maybe 10% of all the fish have it. Its been very hot the last two weeks with much lower wind then is common in NE Oklahoma. No aeration in this pond.
I feed them daily and overpopulation might be a factor on this 3 year old pond. If anyone has thoughts on this I'll attempt to get a picture or two posted...
