tonight i found white fuzzy mold on coconut fiber substrate. crab#1 finished a molt today & crab#2 was fine this a.m. then was found naked and lethargic this p.m. the husband freaked and threw out all the substrate. my questions are... (a)is naked crab dying?(b)any ideas for temporary substrate til pet shop opens?(c) did the mold cause the molt and/or demise of crab#1 & crab#2?(d)why is crab#1 staying upside down?
