Okay so i have a 10 gallon planted tank, some of the plants came with snails attached, i thought it was cool....at first...now the are freaking everywhere....seriously, everywhere and egg clusters EVERYWHERE. what do i do to get rid of these snails? i also have shrimp in the tank and i dont want them to die! There are assassin snails mixed in and i was under the impression that the assassins would eat the others, but nope!
