Mysterious Snail Appeared in tank

[IKeepPacu]

you need to treat the water with a copper based treatment, It will kill any Crustacea but it does affect certain fish species, You will never get rid of them unless you treat. hope this helps

no, he does not NEED to treat the water. there are many fish out there that will happily dine on a snail infestation in a tank, without the need to add any medications or chemicals that will have adverse reactions on the tank and its inhabitants.

snails are a natural part of alot of fishes diet, so he would be much better suited with something like a clown loach, that will demolish any snails in the tank, but can also be easily fed many other foods and thrive once the snails are gone.
