Does my Emerald Crab have brain damage?

I got a small emerald crab today and he keeps flipping himself onto his back and can't get back over. I've flipped him over 5x so far today.

 

Is he going to be a problem child?

I just did some water changes from their tank to mine over an hour period.

 

And again check the tank and he's upside down. Hope he makes it....

hows your params. ? did a quick google search - not too much showed up, but all lead to death. 0_0 some guy said when he had them, his alk was too high and it died.

I'd say consider yourself lucky you won't have to catch it later on. ;)

Agreed, I had a terrible experience with my emerald and red mithrax crabs eating polyps and attacking the goby

My last emerald was fine....I just starved him, and the rest of my tank to the brink of death. I'm recovering from that now and readding my CUC.

 

I was expecting to find him dead this morning, but hes alive! I might have got lucky. The first 24hrs have gotta be the live or die. Maybe he will make it.

After mine killed my firefish in its bolt hole, I gave it to a LFS. Now I only keep snails in my cuc.

Be careful......I added one hoping it would eat some algae I was dealing with. It did eat the algae, and my favorite blasto. And there was definitely still plenty of other food in the tank for it, so it did not turn to the blasto because of a lack of food. Get it out of your tank while you still can. I really do not understand why we still consider any of the mithrax crabs to be reef safe.....

Yep. I fed mine formula 2 and the little leftover bits of mysis and brine shrimp from feeding the goby and pistol. They were just aggressive toward the fish and polyp corals.

Yep mine also ate zoas :( but one day I saw it on the sand, scooped it up in a jar and donated it to a LFS. Trapped it in the jar in 10 seconds using a chopstick to chase it in. It was an unhappy crab.

You guys were right. Came home today and he is eating my red planet polyps.


Maybe I had the weird one before that wouldn't touch corals. Guess he's going back to the store. Will throw him in my QT tank for now.

Wow you guys have terrible luck with crabs, both emerald crabs I've had behaved themselves other than eating some macro algea which is to be expected. Same with my hermits I just think crabs are cool to watch.

 

Where your crabs females or male? I read some where that males crabs were more likely to cause trouble. Both crabs I've owed where female
