My neon tetras have a funny growth on the bottom lips fuzzy cotton looking like , i looked it up and it’s cotton mouth as far as i can tel.i looked for some sort of a cure and i came across esha 2000 and i purchased it , came yesterday , now my dilemma starts as i read the liflet it said it’s safe for plants shrimp filter but not snail. Anyone has any eperience whit it? Does it affect snail as i have 15 horned nerite snail plus loads of cherries 10 amanos !?! Any advice ? I have purigen in the canister but will remove when i treat as i want to treat the whole tank ! Just in case ! I will attache some pics of the tank.
