| Color isn't the way to ID the clam.
Although Dearsa's and Squamosas are usually brown or "gold"
Croceas have a smooth shell, Maximas have scutes on the shells. If you have a purple clam, they are usually either a maxima or crocea, although it still isn't a way you should id clams. Perhaps I can find a link to help with ID'iong clams, hard for me to explain without pictures.
Even with the Squammys I've had good expereince with sticking a small clam shell under the substrate under the general vicinity of the clam when they are in my sales tank. They still seem to attach to the shell. |
