Be prepared to save all of those Nerites after they escape. I had four. Can’t tell you how many times I found them outside the tank drying up and nearly dead. Surprisingly they all survived at least a few months. None lived longer than a year though, and they all died because they escaped.
I would never buy another. And honestly I don’t understand why they are so readily available and so popular.
I haven't had any leave the tank yet, but I have been checking daily! They do look nice...well, as nice as a snail can look! I've read that the caribbean variety doesn't live as long in our aquariums as the pacific variety do, though.
