I'm thinking about getting an Olive Nerite Snail for my 5 gallon planted aquarium, tank mate would be a Betta. However, I can not find much info about them anywhere - except that they eat algae but not plants and can't reproduce in fresh water. Google isn't coming through for me here. I want to know how to take care of them, what size tank they need, food to supplement besides algae, water parameters, what I can and can't add to the water with snails or this snail in particular, and whether they would be compatible with the Betta - if he would bother it at all I don't want to risk it, because the snail would be a pet too. Also, do snails really care if they are the only snail in the tank, would they want company from other snails or don't even notice that sort of thing? Any links that would tell me about them or personal experience would be wonderful! I want to know a lot about them before I decide whether or not to get one, and this is the first time I've really thought about getting an invertebrate seriously so I'm pretty clueless.
