Unidentified TBS crab

[SnappyShrimp]

I found a very small, flat crab among the hitch hikers in my recent package of TBS live rock. It’s pretty pale in color and has a half moon shaped carapace. It seems to have large back legs and smaller legs as it gets towards its claws. It doesn’t look like anything on the TBS hitch hiker guide and I was hoping folks could help identify it or give any clue as to whether it would be safe in a nano reef display (knowing full well better safe than sorry). Currently, it’s residing in the little sample cup but if not reef safe, I’ll dump it back into my TBS hitch hiker/silt bucket.

I have some pics but they aren’t great as the crab is tiny (smaller than my pinky nail).

If I had a guess I’d say a baby gorilla crab. They are super common on these orders. I’m guessing here but the best ones to ask is TBS so I’ll tag them here.

@LiverockRocks what do you think?

It doesn't look like the other gorilla crabs I've found. I couldn't see the obvious black tips of the claws and the general body shape/carapace looks different from other gorilla crabs I found of a similar size. I did find a ton of baby porcelain crabs with my live rock but it doesn't look like one of them either. Hopefully the TBS team may have more insight!

Sorry for the delay here.
Now that is an interesting little crab! Is it located in your sump or anywhere easy for more photos?

Sadly this little crab ended up dying so it will sort of remain a bit of a mystery as to what type of crab it is. Thanks for the response and trying to help identify it though!
