Why do you need drift wood? Is it ok if it’s a different kind of wood?Snails are at home in any kind of substrate. If you have or are getting Nerite snails, make sure you have a piece of driftwood in the tank. Hope this helps.
Oooh, just saw the marimo ball. I'm not sure if they will eat that or not. Someone else with experience with those will have to pop in.
I find that the main source of bio-film for Nerites, is the piece of driftwood. It may not be needed for them to thrive, but it sure gives them a lot of easy access to extra bio-film.
I agree that the OP doesn't need to get driftwood, in order to keep Nerites. I would just like to point out, that I have Nerites in all my tanks, and they spend most of the time on the driftwood, hence the appearance of the white eggs. The OP is lucky, now he has 2 legit opinions on the matter.Don’t necessarily disagree but if someone had a tank with large pieces of other kinds of hardscape like stones or rocks they’d be more than happy to feed on those as well.
I just didn’t want the OP thinking they needed to go out and buy a piece of dw if they want to keep nerites.
