Aquarium Advice Newbie
I came home today to find 4 of my 6 shibunkins lying on the bottom. They will come to the surface to eat, then they go to the bottom and just lie there like they are tired. I checked the levels and the nitrate is just a little high, but all the others were fine. I have had these fish for 2 years with no problem. One has small black dots on his nose, but he has had this for the past six months. After treating them for ich when he first got it, and it made no changes, I just left him alone. As a relative beginner to the fish world, I am at a loss as to what to do. Any suggestions would be greatly appreciated.
