I was originally planning a species only tank ( still debating it) but I thought the snail might be a good clean up crew as well as a nice little pop of color. I don't mind them getting big as long as everyone is happy

Biological filtration? I have an in-tank filter that will be cycled before the frogs go in as well as my tank will be at least moderately planted.

Sorry about my original message my phone was giving me a lot of complications
