pond snails.

I have been researching all the different types of snails and seeing the pros and cons. Do any LFS sell snails. Also, what is better for my 10g a few snails or a pleco?

A common pleco will get much too big for a ten gallon tank. As for snails, you'll have them if you have live plants. Some eat algae and left over fish food, but it all turns into waste and adds to the biological load. Snails are a normal part of most aquatic environments; it's only when they over populate an aquarium that they are harmful.

I'm gonna get some live plants for my 10 gallon i was hoping to get some foxtail and/or some hortworn or something like that.
they look just like the fake plants I have in there now.

Hornwort will grow just about anywhere, and it's very good about metabolising waste materials. Just make sure you get a big bunch of it. Plants seem to thrive when there are lots of them and fail when there are only a few.

If you wanted snails... and you get live plants... There's a really good chance you'll get snails as well!

Snails are known hitch hikers on live plants.

I love my snails that hich hiked on my plants there sooooooooooooooooo cute they just swim around and eat and breed i have like 12 babies in there i love them!!!!!!
