Good or bad snail ?

So even though I tried hard to keep snails out of my tank.. I see that two have made it in. I have been keeping them out because I just don’t know if they are bad or good. But now that I see two I figured I would learn more about it before making my decision to remove them. They are very tiny and must have been in a plant I bought. This is the best picture I can get of one of them. Does anyone know what type it is and if it’s bad? I’ve read some you can’t ever remove because they multiply like crazy!

 

That's s bladder/pond snail and they will multiply very fast if food allows they are classed as invasive

 

Ok thank you! I think I will remove them.

 

Agreed, they are considered invasive. People with puffers would probably take them off your hands

If you have two I'd imagine you likely have more.

 

Pond snail! Honestly, I crush them and my fish and Corydoras eat them

 

Bladder snails. Some people like them, but personally I despise them and remove them whenever I get the chance. They multiply very fast.
