Nerites are wonderful to have if your betta won't pick on it. I have 6 bettas and out of those 6 i only have 1 betta that "obsesses" with the snail. So the snail had to be removed. Nerites are awesome algae eaters. But be warned their bio load is huge. Personally i like the horned Nerites due to their smaller size but they are all really adorable and fun to watch. They do tend to be sensitive to water parameter spikes, so i suggest frequent partial water changes and gravel vacuuming. And check the water parameters every now and then.
Ooh, and bettas can jump. So you might want to think about getting a lid or a cover of some kind anyway, just to be safe. 2 of mine are big jumpers which i found out while doing water changes. Little boogers ended up on the counter flapping. Lol
