crab ID help!

[Introvertedmaniack]

hello everyone! I found 2 little crabs in my tank today. one is pale white and red, so i'm 80% sure that one is a porcelain crab of some sort, but he's too skittish to get a photo of :(
the other crab is a bit bigger and he's the one I'm worried about. he hasn't got the black-tipped claws of a gorilla crab, but I'd still like to hear from people with more experience identify little crabs than i do! these are the best 2 pics i could get of him :/

Definitely a member of Xanthidae, potentially genus Chlorodiella, these are reef safe with caution at best. Probably safest to remove it.

do I need to be concerned about it messing with my other livestock? I have 2 squat lobsters, 4 peppermint shrimp, 3 small brittle stars, and 2 astrea snails (and some surprise living mysis shrimp but im sure those won't last long) :(
also, im not sure if it helps, but it was eating random little things off the rocks earlier and showed no interest in the freeze dried mysis shrimp i dropped in earlier (left in for 2 - 3 hours) or the living mysis shrimp. does that mean its likely that this guys is safe to keep? :0

No I dont think you'll need to worry about it harming any of them but id be concerned for any future coral additions. I wouldn't take the mysis as a sign that hes reef safe.
Since these guys can ne very evasive, id recommend making a trap to get him out, if you have a sump he can live in there.

i don't have a sump, my tank and space are too small, just a 65L tank! i don't really plan on getting any corals or anemones, I prefer a FOWLR sort of style! except with only inverts as opposed to fish. IOWLR? haha! i'm glad he can stay! I'll take good care of him!

Yeah, you just need to keep an eye out and be dilligent. I've had horrible luck with crabs, they always turn on me eventually.

Which is sad, because they are characters and fun to watch.
