I bought 2 C. Dubia from a LFS because the LFS and I were both worried about there condition, they had algae growing on them, they were in too warm of water, and the one last one of its spearing appendages, well after having them for about a week i have some GREAT news, the one with only one rap. is taking silversides like a champ and has lost alot of algae growth that was on it (mostly looked like brown diatom) and the other which had hair algae growing all over it...made a successful molt and is currently hardening the new molt which is why it wasnt eating too well, i have some of the molt including one of its raps, its still pretty small and i will take a picture of it with a quarter for size reference...pics will be up within an hour
