I did a deep clean and replaced all of my sand with Eco Earth. I found 6 dead crabs. All E’s, all new crabs I have purchased in the last year and all died while molting.
Michelle of Naturally Crabby.com and I were talking about this and she agrees that there is something that happens at molt that causes death.
I have had one Rugosus get trapped in it’s exoskeleton and all the rest have been Compressus. This can’t be related to my tank because my other species have never been through this.
I also lost my largest crab, Oscar, to a molt. She molted but never seemed to regain her strength, she was very weak and went naked. I am sad to lose her after having her so long 🙁
