HELP!!! my brand new dwarf gourami seems to be eating my rabbit snail! I can't tell! The snail is normally outgoing but started hiding a lot so I watched and the gourami attacks him it looks like. Can a gourami be violent? Do they eat snails? Do I need to return him? I have a 15 gallon tank its like a year old. I Have 2 frogs 5 guppies a rabbit snail and now a gourami.
