Hi everyone, I have two bettas, one is in a 40 gallon lightly planted tank with several large rocks, and the other is in a 6.6 gallon bookshelf tank with the same set up as the 40 gallon. With the exception of (an explosion) of snails, they are essentially alone. Would anyone be willing to recommend some tank mates for these little guys and some plants that are snail proof? Thanks in advance.
