I have a 10G that I started about 3 months ago. It currently has 3 what were sold to me as julii corydoras. Honestly I am not that concerned with the actual species. My original plan was to have those three with three guppies. Unfortunately the guppies didn't make it (note not everyone was added to the tank at the same time). I have decided to stick with the corydoras because I really like them. But I would also like a snail. So my question is... in a 10G can I reasonably do 5 of this species of corydoras, plus a snail? Also any snail type recommendations?
