20g too small for a clam? (Maxima/Squamosa)
 

is that too small?

croceas and maximas grow to about 9" ....more light thirsty and less forgiving of water quality...they seem to prefer being on the rock......


derasas and squamosas can grow past 20".....less light thirsty and more forgiving of water quality....seerm to prefer being in the sand

Thanks for the info. It would probably take up too much space Haha. Maybe in the future if I move into a bigger tank
