Are there any snails that can live in a tank with a sand base? I have setup a 10 gallon tanks with a sand base (I want to get a female betta for it, but right now that plan is on hold indefinitely because I am using it as a hospital tank for an injured Tetra) When I put some snails in it they all died in lest then a few hours, the tetra that is being rehabbed in it is doing fine, so I know the water quality probably did not kill the snails? So is there any snails that can live in a tank with sand?
