[jeff williams]

i have the same thing, do i need to do anything to get rid or them or will they go away themselves

 

[Blurrsvision]

I have the same exact type, any updates?

 

[jeff williams]

I’ve just been watching them to see what happens I haven’t seen them spread they still look the same as before. Being there on a trochus snail in my qt I haven’t worried to much but when the opportunity arises I’ll pluck him out of the tank and Rome was them off his shell

 

[jeff williams]

I just been watching them they haven’t spread and beings there on a trochus snail in my qt system I’ll wait for the opportunity to get him and remove them from his shell

I have had these in a tank before and they just went away on their own. JP
