What Is THIS???

[jzuse]

What is this thing in my tank?

I am sure that it came form the LR. What should I do? It is about 1 1/2" long.

 

[reeffer]

its most likely a worm or snail, possibly nudibranch

 

[joksta]

i would say nudibranch
i think i have seen one of those in my local fish store

 

[jzuse]

so it sould be ok to leave in the tank

some nudibranches will eat coral. Is yours a reef tank?
