Two of my angels have developed a round wound on the side of their bodies. You can see the flesh underneath in a perfectly round circle. I have had no luck diagnosing this. I thought of HIH disease, but this is on the body and my water and diet for them is top notch.
They still eat & swim normally, not hiding either. One died suddenly,& the other is in hospital tank. I don't know what the treatment should be for this.
If any of you have experienced this, I would greatly appreciate some advice.
FYI: this is a 75g S.A. tank with 6 angels, 6 german rams, 6 bolivian rams, and 6 apistos.
