White thing on betta tail. Flukes? Remedies?

[hannahc513]

Hi guys! I’ve noticed for awhile my poor Winston started looking a little raggedy after I attempted to breed him. His fins never fully recovered and this was months ago. Now I’m starting to notice this white bump on his tail? Can anyone tell me what it is and what I should do to treat it? I can’t find anything online and I just want him to be healthy again! I’ve included pics and the last one is on the other side so whatever it is it’s going THROUGH his tail. Help please!! Thanks in advance

Probably Lymphocystis https://en.wikipedia.org/wiki/Lymph...rowing small,fins, and occasionally the gills.
