Bella goby tail

Hey everyone

My Bella goby’s tail looks a bit weird. Levels are fine. Eating and digging like it should. Maybe fish aggression?

Thanks!

Looks pretty large to be an injury, but maybe. How long have you had the fish and did this develop overnight, or did it grow slowly over days?

it’s hard to tell but I think over a few days after I moved some rock around the tank.

The other possible diagnosis is Lymphocystis, a mild, non fatal, non treatable viral disease that will go away in a month or so (may get worse for a time though).

Injuries are usually “subtractive”, the injured area loses tissue. Lymphocystis virus causes the skin cells to grow larger, so the whole lesion looks bigger than the original area.

Will that spread to other fish or should I just monitor?

I appreciate your time.

It can be contagious to other fish, but almost always, only newly acquired fish of certain species. Long term captives have almost always been exposed to it. Think chicken pox in people....

Would you recommend putting him in quarantine? He’s pretty slow. I could probably scoop them up. He’s not afraid of my hand or the net.

No - if it isn’t lymphocystis and is something else, moving it now won’t protect any other fish as they’ve already been exposed.

will do thanks I’ll monitor.
