My Kenyi, which I've had for 4 years, developed a bump on one of his nostrils a few months ago. I gave him time to heal, but a few weeks ago, one bump became two bumps. He lives in a 55 gallon tank with a Chinese Algae Eater and a Electric Blue. My water quality is good. The tank is planted, and I do frequent water changes. I treated the Kenyi and the Blue for mouth rot a couple weeks ago with Triple Sulfa. The mouth rot may have actually been battle wounds. In any event, both healed and were returned to the 55. The Kenyi's bumps were unaffected by the triple sulfa. In the last couple of days, the Kenyi's bumps appear larger than ever, and he has been spending more time near the surface of the tank. After consulting with my local fish store, I decided to give the Triple Sulfa another go. I am operating on the suspicion that the fish is afflicted by some sort of bacteria. The bumps are solid and white, and they appear to have small blood vessels running through them.
Any suggestions? I will try to post a picture.
Thanks,
