Im not sure if you mean the snail in the center of the picture or on the right?View attachment 208593
He’s a ramshorn snail, right? He was moving, so I’m guessing came in as a tiny thing and has been quietly cruising about. Surprise crustacean 🙂
The center one looks like a Melanoides snail, Malaysian Trumpet Snail.
Impressive shell length, your water must be good for snails 😃 In my tanks the shells never got that long, too soft water I think even in low tech.
The shell color of it is cool too, usually the common ones (at least in my country) are beigeish brown with dark stripes.
But I have seen on some german websites that there are a few different color variations available, varying degrees of brown, I think one is called Mocha /Mokka.
There are even black ones, which I think are the Melanoides maculata species.
The snail on the right in the picture looks like a Mini Ramshorn, Im not sure the hobby agrees entirely on the latin name but sometimes described as Planorbis sp. or Gyraulus sp.
They carry their shells flat on their back, and dont get very large compared to a lot of the other common snails 🙂
