Hi my names Dave and I,m new to this site and love what I see,what a wonderful source of info. Anyway I,ve been keeping f/w tanks for about 3yrs and s/w for about 1 1/2 and I,m hoping to convert all my tanks to s/w in the future. I,m retired and disabled from the service so this is about all I do now [6 f/w tanks and 1 s/w ] I love my s/w tank its a 29gal and fish wise I have 2 clowns and 2 damsil,some nice button poylips and some star,s also.i also have 1 brown leather,a frog spawn,1 orange brick sponge 1 candy coral, 4 flower anemones and 1 pink tip anemone. 2 turbo snails and 5 emarald crabs and 2 sand sifter star fish. yeah I know its alot for a 29g tank but everything seems to be doing good except my green buttons sometimes seem to loose they,re green center and turn white in the middle.I have a 130w compact light a filstar xp2 filter and a sea clone skimmer oh yeah 30lbs of live rock as well. Anyway I really want to add a clam to my tank but my lfs say I have to have m/h lighting to keep a clam, I want to know if there is any type of clam that I can keep with compact florecent. Any advice and I,d be grateful. thanx all
