Is This Sphaeromantidae Isopod?

I saw this little guy on my aquarium glass today and I was thinking it's a harmless isopod from the sphaeromantidae famly... am I right?

What does the top look like? Is it segmented or cone shaped with a hole in the top? It is more likely a Chiten or a keyhole limpet (diodora sp). The isopod would have legs and not stick to the glass like that.

It looks like it's segmented, it looks like a chiton but I didn't know they come in that small size.. this one is about twice as big as a copepod...

I have seen really small chiton the are harmless and eat algae.

The Sphaeromantidae would have a set of dark eyes and antenna at one end that is easily seen.

Thanks a lot! The chiton is still on the glass eating

You are welcome. That is a good spot for him.
