Are Bladder Snails A Pest Snail?

I got a Black Racer Nerite Snail and 4 weeks later I see 3 baby snails.I assumed they are baby nerites but then I realized that they need brackish water and they are supposedly bladder snails (I searched s and they look bascially identical). I also have very tiny snails with a yellow colored shell so if anyone might know where they came from, please tell me. What I have in my tanks: Anubias, Elodea, 1 Betta, 3 Tetras, 1 black nerite, and a gold mystery snail that died 10 days ago <--. I just don't know if its a pest or mystery snail (there are like 14 of them).

If in doubt and you don't want them taking over your aquarium, transfer them over to a random container of 2.5/5g and watch them grow

 

How would I be able to transfer them? They are too small for me to eye out and even if I do, that's just 1 out of some 14 snails.

Just pull our any you see and put them in the container, then keep pulling out any you see each day until there are no more to pull out!

 

Yep. They survive in high ammonia levels too, very hard to kill. My friend got some plants in the middle of cycling, they had bladder snails on them. The ammonia was something like 5 ppm and they still lived. If you have pufferfish they will love a snack too. Whenever you see one, just grab it and take it out and you should be fine

 

Bladder snails are pest snails. Mystery snails take two to reproduce and lay very large and obvious clutches above the water line. Some nerites are small with yellow shells, but if you could take a pic of the yellow ones, we could help ID that.
