| I am NOT a clam person, so I don't know for sure, but maybe IF you can get the clam up high, close to the lights...
I believe some clams like being in the rocks, while most like being on the sand bed. Not sure about the derasa. You keep coming up with high light loving animals for your tank. Maybe you should just go ahead and make the upgrade to metal halides. Then, you will be able to keep just about any of them. |
