derasa and crocea

[dmbnpj]

Do the two of these type of clams like heavy/light/ or no water flow?

Thanks,
Jeff

croceas can handle more flow than most clams, deresa like a moderate flow

should you put flow to them if possible? or are they ok at the bottom of the tank? most flow is in the middle to the top of the tank.

Croceas like to be in the rockwork. If you want to keep it in the sand(if you have enough PAR in the sandbed for a crocea), get a flat piece of rock that it can attach to then put the rock in the sand. Deseras are sand dwellers and should be kept in the sandbed. Croceas need lots of light, Desera dont need as much. Since clams are filter feeders to, its always good to have some flow around them. Just dont blast them. What is your light setup?
