Hey Guys, My wife and I are new to pond ownership and unfortunatly didn't find this site until after we had established our pond. We cleaned out an old swamp and damed a small creek that ran thru it creating a small pond that is about 40 x80 feet long and no deeper than 5 feet. We stocked 150 hybrid bluegill fingerlings and 25 catfish fingerlings the first fall and since it is a natural creek we have an adbundance of creek chubs in our pond. We also have 18 Koi that outgrew my moms plastic pond which range from 10-20 inchesplus 3 larger catfish which were about 10 inches when we added them to the pond last year. My question is.. we have found 3 smaller (3-5 inch) bluegills floating in the pond this week with what appear to be either red sores? or bite marks on them. The one we found yesterday had a two red lines about 1 1/2 inches long on either side of its body about mid way up. Do I have a diease problem or it this what fish look like that have been attacked by the catfish?
