Can anyone help ID these two.They arrived with new live rock for my refugium I've just built ,they're out after just 2 days in the ref. I think 1st is a type of sponge?
I can't tell on the 1st pic, but if it is a sponge, they are harmless filter feeders.
The 2nd pic is some sort anemone, but doesn't look like a mojano or aiptasia.
