Hi guys,

This bump has been on my Chancho’s tail for well over a year. I do 50% weekly, don’t overfeed, and haven’t had any issues with water or fish since the two years it’s been cycled. Because of these factors, I hesitate to say that it’s Lymphocystis as folks on other threads say Lymph goes away relatively quickly and can also be caused by netting the fish (hasn’t been better since I put him in the tank).

Anyhow, here are some pics for the experts on here…Thoughts?:

(Thanks for your time, btw)

Looks like lympho or like an injury never healed properly. My severum has a big lump on the base of his dorsal fin for likely similar reasons. Lympho doesn’t always go away fast.
 
Thanks Deadeye Deadeye anything that can be done? It’s pretty unsightly. I just don’t want it to be a parasite and start moving headwards.

I wasn’t ever able to do anything about the sev.
If it doesn’t seem bothered there probably isn’t much to do.

Maybe just scarred up since being there so long. I’d leave alone if there for a year and not active.
