The large one is probably a chiton. The smaller, harmless isopods.

The large one for sure looks like a Chiton. Total algae mowers. I have had some in my tank that I found at the beach for a while now. No issues so far, have sps, nems and zoas.

So not an issue ? Do you guys suggest transferring then to the next tank

I don't see why not. Any harmless, algae mowing critters are a good thing to have around. They are kinda cool in the wild cause they will suction to rock and then the tide rolls out and you can find tons of them all over the place. Really hard to pull off rock once they clamp down if you don't use the right method.
