It's a mystery...

I'm thinking about adding a mystery snail to my tank of three leapin' loungers. The snails clean up the uneaten food and help the tank stay clean between cleanings. I have a few little snails that came with Gherkin's little set-up, but now that I have a larger aquarium for the new boys, I think I'll add a larger, more colorful snail--like the mystery snail!

Well, and one more frog, too...maybe
