Hi. I have bought 5 emerald crabs 4-5 days ago, and I noticed they started dying. I have scooped 1 out already and I think one more died also. I checked my water levels and they're all fine. Can someone maybe tell the problem? Or if there is a specific way to take care of them?

55 gl. tank
est. 50lbs LR
est. 15 red-legged hermit crabs
2 sally lightfoot
4 emerald crabs
1 sponge crab
1 sailfin tang
mushroom coral

Coral life lighting
Seio power head
Jebo canister filter
Ramora protein skimmer
 
Did you acclimatise them properly?
Are you sure there dead not just a molted skin as crabs/shrimps seem to molt soon as they enter a new tank due to the change in water etc
if not you may have a large hitchhiker crab that you don't know about & that maybe killing your new emerald crabs cant think of much else that could be wrong how come you bought five do you have a lot of bubble green algae you want rid of are you just liked the look of them..

if they are dying & you want some different crabs try a sally light foot

noticed you already got sally light foots sorry

sorry but what do you mean by acclimatise? and a hitchhiker crab what is a hitchhiker crab? I am pretty sure they aren't molten off. Would a hitchhiker crab harm the sally lightfoot and a sponge crab?

im pretty sure when he says hitchhiker crab he means anykkind of larger or destructive crab that cam along with your live rock.

by acclimatise, im sure he's refering to the way they are introduced to the tank. its always a little trickier with inverts than it is with fish. Inverts tend to be more sensative.
 
Acclimation is the process by which you gradually adjust your livestock to the water conditions in your tank. Too rapid a transition can result in shock and, in some cases, death. At this point it would be too late for this batch... they've already been exposed to the new water conditions and there's no way to take that back. Hopefully the last two will survive and (particularly) it's not the result of a disease.

Someone can better explain the process than I, but check out this link. For an invert and other sensitive creatures, you should be using the drip method. I'd mention it to the place you bought them from. It's possible they'll give you some new stock but, if so, please make sure to acclimate them appropriately otherwise you're likely to just have the same problem.
