I currently have a guppy that has large masses on its tail, and quite frankly I'm not sure what it is. The guppy originated from a 20 gallon tank that had 4 other guppies and one dwarf gourami. I was out for a time and couldn't do water changes, and when I came back everyone had mild fin rot except for this one guppy, with the very odd looking tail. The tank has been running for a year, is fully cycled, and is kept at around 75-78 degrees F. The fish acts fine other than the tail. Still eats, etc. but I can tell the tail is affecting him because it looks quite heavy. He has been like this for around a month now. When I first quarantined him I did kanaplex for a bit, but because of how busy I was at the time, I wasn't able to complete treatments or have a consistent dosing schedule. For around a month he's just been in a 5 gallon quarantine tank. The masses have gotten a bit bigger. One of them looks to be a cyst as well. Like a little bubble on his tail, and a few times I saw that supposed cyst turn bright red. Advice is most wanted, I certainly am quite attached to this little guy.

That might be Lymphocystis, a viral growth. Its fairly common. No cure; not very contagious. Occassionally the infected fish's immune system will supress the cyst. Sometimes it continues to grow.

It looks fairly similar to lymphocystis. What would you recommend as a course of action? Since there is no cure, should I just make him comfortable? I am hesitant to put him back in with the others. Anything I can do to help?

Lymph. Is a virus, so meds have no effect. Its your call on what to do with the poor guy.
I've only had to deal with Lymphocystis once. I kept the infected fish in the main tank for months. The growth kept getting bigger and I eventually euthanized the fish. No other fish caught the disease.

Ok, thank you. I will decide on what to do next.
