I have a 5 gallon fish tank, home of around 15 guppies, 4 pladis, 1 white tetra, 1 marble hatchet, 2 neon tetras, and 1 algae eater (about 2-3cm long). Anyway, recently I bought a plant for my fish tank so the babies can go up and hide in it, so far 2 babies have survived because of it, but in some way 2 snails have entered my aquarium. They might have been eggs on the plant I purchased a few weeks ago. Anyway, they're tiny little guys. I first saw one climbing on my glass. It's a little bigger than a pebble. Last night there was only one. Now there is two. And I'm pretty sure they're mating. What should I do about this? Take them out? I don't really have any idea how to take care of snails.
