I used to keep 13 clams in a 65g haha. I had maximas, deresas, croceas and squamosa clams. My fav out of all are now prob the smallest maxima clams from the coco islands. Here is one i recently purchased
I've tried maximas twice and they never lasted more than a month. Could never find out what killed them. I'll try again in 6 months after I have the 180g up and running if all goes well. I really love them!
I've got two French Polynesian maximas in my frag tank. One is pretty big, the other a bit smaller. Clams are one of my favorite reef dwellers, but many people get them, and are not aware of what it takes to keep them happy and healthy.
I've not kept a clam ever although I've always loved how beautiful they are....I've always been intimidated by their price (for a decent sized one) and their propensity to use a lot of calcium. I also have a coral beauty and am worried that it might pick at a clam.
id love to have a nice clam ...but the choices in the northern panhandle of florida for LFS's with any selection is dismal ...and for me I really want to be able to see a clam in person before purchasing... I had a tridacna gigas about 10 years ago and loved it more than any maxima... they seem to be a bit rarer these days.
