I bought an established small tank and I pick it up in a few days. It is a 20g with 25#LR, some softies, a Sebae anemone, a maroon clown and six clams: a couple squamosa, three crocea and a maxima (all are 2"-3.5"). I have never kept clams before but I have always wanted to. Can someone point me in the right direction on their care? I plan on buying the giant clam book, but it probably wouldn't arrive until a few days after I need it. I need placement tips, feeding tips, compatability tips, etc. I would also like to get a six line wrasse, do you think it would get along with the clown in a tank this size? Oh yeah, there will be a 250W Iwasaki and a PC actinic over the tank. I could put this stuff into a 29 if you think this is too crowded, or another thought is to move some of the stuff to the 150 I am setting up.
