The picture has not gone thru :( but to clarify, the blue guy (which size is he?) was on the surface, out of his shell and his limbs were all around him? Another crab could've dug him up but if he was molting when he got dug up, technically none of his limbs should be apart from his body, just a partial exoskeleton. Another crab might have attacked him for the shell maybe? Also if you really want to send a picture you can email it to me avamin2005@icloud.com but that's a bit overkill haha

blue guy is a tiny to small, he just changed shells yesterday. the crab he attacked was a medium, which went down to molt like two weeks ago. also how do I post a pic? and I found both partially under a rock

Sorry hang on, so the crab that was attacked is the blue guy or the medium guy? From what I can understand, the blue guy was about to molt or preparing to molt, and the medium was already molting and the blue guy went down and attacked him.

Okay, so I think they probably had a fight or something, or possibly it could be the result of a molt(s) gone wrong. Most importantly: where are they at right now? Have both of them gone back under the substrate? If they have gone back under, you can assume that they r probably molting and should be okay. If not, the crabby missing a bunch of his limbs might need some extra help getting around (I know some people that are great with injured crab tips)

Also, if the white shell guy is under the substrate even though he lost his limbs, I would recommend moving the blue shell guy to an iso tank to prevent him from attacking white shell guy again.

Blue shelled guy moved to another spot, but I checked the white shell and theres no one inside. I isolated the crime scene with a cup, but from what I saw it looks like the white shelled crab was eaten because I see gel like limbs:(

oh no! :((( that really sucks. In that case, I'd probably get rid of white shell guy's old limbs, don't let blue shell eat them too because he might develop an appetite for his friend :(. Are there any other crabs in your tank? Might want to take precautionary measures for them to protect them from blue shell crab. (maybe when a crab goes down to molt, you can iso tank them so blue shell won't attack them like he did to white shell)

everyone else is down right now except for the large crab, I'm setting up a iso tank for blue shelled crab right now so he won't do the same:(

Yeah, iso tank sounds good. Tbh, I don't think that eating his friend was an act of aggression, I think he may have been hungry. While the blue shell guy is in his iso, maybe introduce a higher protein and calcium diet? Another idea; it might be bothersome, but every time a crab goes down to molt, you could move the blue shell guy to the iso in order to protect the crab that went down.

yeah i don’t think it was a act of aggression either, but rather a diet problem. im ordering a variety of new food so this hopefully wouldn’t happen again

I'm so sorry this happened to you :( Like avamin2005 said, I think an ISO would be a good idea, and your crab was probably just hungry.
