What might this be?

[Kjames]

Bigger than the flatworms in my refugium. I’ve counted 5 or 6 of them, this one being the largest. ID please.

Chitons?

Limpet?

Looks like a limpet... need a picture of the shell top for positive ID

 

[ReeferWarrant]

Agree, looks like a limpet

Looks like a limpet although a top down shot would help confirm (if possible). Nice score if thats what they are, awesome little algae eaters

 

[HOOPDEEZ]

I agree with limpet, nice self populating cuc

 

[Kjames]

Thanks, all. I’ll try for a top down shot. Interested in these guys. It looks like a handful of them are present in the sump.

Definitely limpets, super cool CUC. Nice find!

I tried to slide one off the glass but he wouldn’t budge! Here are a few pics. Turns out there are quite a few between the rollermat and fuge sections of my sump.

100% limpets!

Thanks everyone for the input. I sure do like it when something cool shows up in the tank.

Thanks, @AlgaeBarn for chiming in.

On a related note, I added a couple of batches of your 5280 pods to my tank early on after the cycle and have been really impressed with the pod population ever since. My refugium is literally overflowing with pods. Only wish I had bought my Chaetomorpha from you. Locally sourced stuff came with some surprises that I would have just as soon avoided.
