Unidentified Aquatic Snail

[WiNd08]

Hi all !
Went to Pulau Tioman over the week and collected some snails from the waterfall.

I wonder what species they are as I've never seen them before. They are solid black in color and I introduced a few into my tank, and to my amazement they can scrap off hard algaes on my glass (I can see that they leave a track where they've been).

Very hardy snails and they max at about 1inch in size.

Looks like some Nerite species (Neritidae). Are you sure collecting snails from Tioman is permitted?

The area I was collecting from is not under the protected area and I asked my guide before doing so

Will try to find out what is the exact species of the snail
