A trio of critters

[reefruss]

I found these characters in a shipment of corals I got today. I'm naturally reluctant to include things like these into my tank until I know if I should. There were three in the shipment and one looks like a snail like creature with a hard shell on it's back. I have found one of these before and they can be really difficult to remove once alerted. I was quick on this one and got it first try. Any guess what these are and was I right not to include them?

Looks like a bristle worm a fire worm and a chiton?

Stomatella snail and some worms?

Some people like the snails, as they are harmless. I generally exclude worms but others keep them for clean up crew.

 

[reefruss]

Would you put them in your tank or not?

 

[reefruss]

I don't think it's a chiton, it has a smooth shell not serrated.

 

[Copingwithpods]

Would you put them in your tank or not?

I'd hold off until someone id's all 3 before making that call.

 

[reefruss]

It does look like a Stomatella snail and apparently they are good for the tank.

The stomatella is great, the worms are up to you, bristle worms are good cuc as well.

Don't put back this worm in the tank it feeds on corals.
