I’ve had my cleaner shrimp for about 3 months. A couple of weeks ago I noticed a black spot on its side. Later I caught it picking at it. The spot disappeared after it molted but reappear a few days later. It’s on the shell/exoskeleton. It seems like a sore or would. I have an BTA. Could it be a sting? Should I worry about infection? Is there anything I can do to help?
Thank you!
