Snail

[ella777]

I had both the zebra nerite and the black nerite snails, over time I found out the black nerite snails to be easier to keep and can get quite big, bigger than the average man's thumb fingernail. The oldest I have in my tank are about 3 to 4 years old

Oh okay, maybe that's what I have then? Just coated in algae haha

My zebra nerite, which is four years old, is 2,5 cm long on her she'll, the foot is longer. But they tend to hide the foot of others nip at them.
Gently coax it off the glass, use a soft toothbrush, scuba it very gently in circular motions of the shells. It is just aesthetics anyway, the snail doesn't mind

I finally got a picture of the shell and the white blob.

That's one of the nerites, commonly called black nerite or black helmet nerite or military helmet nerite. Scientific names are a mess with sites using the same one for different snails.
The white spots are nerite eggs. They'll lay eggs on anything, including each other

Okay thank you, but what is the white blob on its underside? In the second picture, near it's strange looking mouth.

Another question, is that its teeth in the mouth? I know it's nothing bad but are they teeth or grabby things

The mouth things are for rasping algae off things. If you look carefully at the glass you'll see the pattern it makes as it scrapes the biofilm off the glass.

I have no idea that the white think on the underside is, though it doesn't seem to be bothering the snail. It wouldn't be able to crawl up glass if there was a problem.



One thing to warn you about nerites - if they fall off something they end up on their backs and unless there's something nearby to grab hold of they get stuck like that and fish tend to try to nibble them. I have a stick next to my tank to flip them right way up, or at least push them against something they can grab hold of.

Oh okay, I won't worry then.
I usually flip the snails over if they ever get stuck, so no problem there but thank you!
