    Smallest Clams

    Hey all,

    I'm currently setting up my 10G nano tank. I was wondering which clam type would stay the smallest (or grow the slowest) that I could keep in my tank. I won't be introducing it into the tank until the tank is fully established and that I'm sure everything is o.k and ready to accept it. Any information would be appreciated.

    Thanks,

    Steph

    The smallest Tridacna clam species is the Crocea.
    However, I don't know if a 10gallon is large enough.

    How fast do they grow? I've seen people on nano-reef with some in their tanks.

    I am no expert on clams at all, as I have never owned one. From what I have read, clams can grow pretty fast as long as their light, food, and calcium needs are being met. I have also see nano tanks with clams in them. I'm not sure how long they were able to keep the clam in the nano though. Also the smaller the clam the more phyto you have to feed them, as they cannot get enough energy from the light.

    the problem with keeping small clams in a nano is that the baby clams need phyto planckton and other small food types which don't really exist in a tank. basically, under around 2-3 inches clams filter feed, after that they can rely on light. tiny clams usually die in captivity so you'd have to get one at least 3 inches. Croceas stay the smallest but they also require the most light.....I think what I am etting at is that it probably isn;t a great idea to keep one in a nano. Deresas are probably the most forgiving but they can get to be up to a foot

    Crocea's will grow up th 7-8"... they are the smallest of the tridacna sp.

    What's been said above is also true. Clams smaller than 3" need to be fed. A LOT. It would foul a nano in no time. Which means that you'd have to remove the clam and place it in a bowl to feed it every 2-3 days. Some clams don't respond well to being handled all the time.

    From all this info I'd say leave well enough alone and left a clam for a bigger tank. But thats just my two cents worth.
