I tried my best to take macro shots.. and if you can't tell the yellow sac-like thing near my pleco's mouth also has a black dot in each sac.

I'm not sure if this is where plecos store the eggs or if this is some kind of mouth rot. Any help would be appreciated and how to remedy it.


Tank stats:

- 20gal tank
- 1 sm. goldfish, 1 feeder fish, 3 sm. plecos
- airline bubbles and AC70 filter

Answer 1

its a disease not fatal to fish my pleco has the exact same thing like yours right now, the name is Lymphocystis , it has to do a cycle of about 4 weeks or and then starts to reduce till its gone , my pleco had 1 of his 2 sort of fangs and in his mouth covered but seems to be reducing now, i wouldn't worry too much coz the pleco is the strongest fish i had ever had in my aquarium, please keep me updated how yours is doing too
