| With your lighting I would definitely stay with either a T. derasa. The hippopus clam is not colorful at all and is also referred to as the rock clam. They look that much alike.
The derasa is colorful in oranges, tans and usually has a bright blue rim around the mantle.
One thing I would tell you to watch is your coral beauty as it may try to nip the clams mantle. Some are trying to pick at the clam and some are only after slime that is on the mantle.
I don't know if Petco had any derasa clams but that is the only one I would suggest. With your lighting you could also care quite well for a squamosa but they will get big and would soon out grow your reef system. Obviously that would not happen overnight but you might want to try a squamosa also. |
