How large is it?
Where did you find it?
What could it have come in on?
Do you know if it's eaten anything?
How does it behave?
Is it fast or slow?

Thanks for responding. This tapatalk app is terrible and I wasn't sure if it came through. ...this little tank was purchased complete from a guy who ]was moving. Said he ordered all live rock and livestock online.....in my 3 weeks of owning it I've discovered a spiny oyster, some kind of mollusk, two large chitons, and now this. It was early morning lights out. Looked like it was looking for algae on the glass. Slow mover...about 2 inches but stretches and such

It's a chiton- Cryptoplax larvaeformis.

Hey, my LFS has one of those in a nano tank. It stays underground most of the time.
Man, that tank has a lot of awesome hitchhikers!

It's a Cryptoplax for sure, and is harmless. Whether it's C. larvaeformis...that's probably still up for debate.

Cheers,



Don
