I fear Flatworms > confirm ID?

[Ismellikefish]

I came home with the lights off ( dark ) and saw 3 of these things in my tank. I think they are flatworms but I want to confirm them.

The center is hard and was suctioned cupped to the rock/glass
The outer "skirt" is paper like.





Thanks in advance

Look like Stomatella sp. snail.

[Sk8r]

possibly stomatella, possibly nudi. If it has a saddle-like shell-plate and long antennae, stomatella, if otherwise nudi or even chiton. Doesn't look flatwormish to me as of these photos.

[Ismellikefish]

Yes saddle like and has 2 antennas

so it must be stomatella > they bad?

Those are Scutus, a type of limpet. They're harmless.

[pledosophy]

put them back in the tank, they are good.

FW's are about the size of a fat pencil mark maybe 1mmX2mm or so. also the crazy ones are sort of rust orange colored.

[Crazy4salth2o]

Agreed...not flatworms

[LeslieH]

Mike's right as usual.

As been mentioned, they are scutus and are harmless *UNLESS* you have members of the pocilloporidae family (such as Pink Bird's nest).

I had to remove mine for that reason.

The top one in the first picture sure looks like a Stomatella. It seems like I can even see the shell on the outside. It does not look like the Limpet you are referring to.

The top one is the one that made me think Scutus more than any of the others. Scutus do have white shells but they shroud them with a black flap most of the time. Under stress you usually see them better.

[Paintbug]

thats a Scutus for sure. They are also called fleshy limpets.

[just dave]

I've seen them but that one looks like the shell is on the outside.

[pagojoe]

The shell IS on the outside if you make them withdraw the mantle, just like cowries and marginellids and lots of other snails that have glossy shells. Scutus don't have internal shells like sea hares.

Cheers,
