No. Snails die, wait for the ammonia, nitrites and nitrates results.Is there any medications safe for fish that will kill off the snails? My tank is getting over run with snails that I didn't want in the first place.
It is not. A lot of coins contain other heavy metals which is dangerous to the fish. Consider this one of the worst methods on the same level with the chemicals.i read that if you put a penny in your filter they will all die bcuz they cant stand copper. but im not sure if thats safe for the fishes
