Lympho? Fungus?

figgins5 · Feb 12, 2024

Hello- New to the forum and looking for some advice/help. I recently added a bi colored angel and noticed spots around the fins and gills. Spots grew in size over the past few days and now resemble cauliflower. I attached a video and some pictures. I have tried to QT but have been unsuccessful in catching him. Respiratory rate looks good but has not been eating the last week and hiding more. I did treat DT with Prazi for a 5 days. Did a water change and ran carbon. All other fish are fine and eating well. (Fish only w live rock). I did some research and looks like Lympho. (No treatment) but wondering if it could be bacterial or fungus? Newish to the hobby and appreciate the help!

Welcome to Reef2Reef!

Unfortunately, that isn’t Lymphocystis. See how the lesion on the belly is erupting from under the scales? That means this is an internal infection. The rapid breathing and not eating means the infection is systemic (far advanced).
One common cause for this is Icthyophonus hoferi, an internal fungal infection. Sorry, but that is not treatable. Luckily, it also does not seem to be highly contagious to other fish.

Thank you Jay. I appreciate your response. I will hold off on any treatment and just focus on water maintenance and health of the other fish. Do you think it was a good chance he had it before I put him in my DT? Also, any suggestions on meds for QT to prevent most common illnesses that have worked for you? A lot of different opinions. I am learning through my mistakes and the mistake on this guy was no QT (will do for all in the future. Have just got lucky to this point) Thank you again!

I can't say how/when that infection occurred, and I'm only guessing Ichthyophonus based on the way the lesions look.

Going forward, here is a link to our current quarantine protocol:
