snail id

[tirkin]

Hello

Could somebody id this small snail about a size 1cm.
I got 1 of these with live rock about 2 years ago, but now I can count at least 10 of them, so they have been reproducing

It's an Engina species, although there is still some disagreement about it's proper name. It's had several names in the past, and has been considered to be a form of Engina alveolata, but others believe it deserves its own name, Engina histrio, and isn't a form of that species. They are found in the same areas without intergrading, and E. alveolata are about twice as large and have orange and black markings instead of yellow and black ones. Your choice:

You could easily have gotten a piece of live rock with ten (or fifty) juveniles of this species, as they are often clustered in the holes and cracks. They may have just grown up and become more visible.

Cheers,



Don

Thank's a lot for identifying. Some of them do like to hide in crannies of live rock, sometimes couple of them together.
Well, I guess these kind of snails don't reproduce in an aquarium, but if they will it would be great

I have found 2 more a lot smaller ( 3-4 mm ) juvenile snails from my tank. I have not added any new live rock so it could be that they have born in the tank. I hope to find more of them.
