Red sore/bruise under clownfish mouth
I have a mated clown pair that are in quarantine since 8/10 and been treating with Cupramine since 8/15. The large clown female has developed a small red sore or bruise under its mouth. Its hard to get a good picture of the sore. Any recommendations on diagnosis and treatment for this? Considering using an antibacterial medication but not sure which would be best in this case.
