hi, i just bought 2 red claw crabs about 2 weeks ago and they were doing fine. i just had my water checked and everything was good. however, 1 of the crabs just molted 2 days ago and was doing alright until about an hour ago. 2 of her legs fell off and she just ripped off 1 of her claws. why did she do this?
she is still alive so if anyone could give me some info fast, that would be great.
thanks

did you leave the molt inside the tank? almost all types of crustacions (shrimp) and crabs consume the molt because of the need of calcium

Planted 20 gallon
2 emerald corydoras
2 gold barbs
2 cherry barbs
4 swordtails
2 platies
1 balloon mollies

they did eat it, and i actually figured out the problem. the other crab attacked her and so she lost the 2 legs and a claw. the other crab then took off 2 more of her legs so shes done to 4 legs and 1 claw. im putting a tank divider in so that this will stop and she wont die.

I have 3 RCC and yesterday 2 of them molted. The other one molted about 3 or 4 weeks ago. None of them even tried to eat their old shell so I took them out (their on display now) the 1st one to molt only had 6 legs and one claw before he molted. Now he is normal. I have them in brackish water. All 3 of them are doing great, active eating and doing their normal mess making in the tank. They have their own tank. I have one male and 2 females. I add this because I know the males will fight each other. Thats why I made sure I got only one male in the tank.
