    A derasa prefers to be on the sand. Why do you want a derasa specifically? Seems like they get pretty big for a 34g. Up to 24", but they also grow fast. They can double in size in a year. A It's your tank, so your certainly free to stock what you like, but it seems like a crocea or maxima might be a better fit.

    I personally think trying to keep supplements stable in a 34gal will be a nightmare when that clam starts to grow.

    Hello I have Derssa in a 45 gallon, was in a 29 gallon- this is also my coral tank, my clam is close to 8-9 inches,started at 5 -6 nearly two years ago. He host's a pair of True Percula Clown Fish, oddly enough- and he loves it. :)

    I do not think those lights are sufficient, as well, the Deressa prefers the bottom of the tank- in the sand- at least 2 inches in depth, any where else he will die.

    The reason for this is because they like to move around, unlike many other clams. Many times a day you will see this behaviour when they "expel" water to move themselves- this is so they can repostion themselves to their "comfort zone".

    As for size, they do not grow 10 inches a year maybe 2 at best, so if size is a concern worry not. Yes they get big in the wild, (and in captivity) but those clams are many years old.

    Water flow and good lighting- and a min. 2 inch substrate base is required to keep these guys. Have care what fish you buy as well- certain fish can become a problem. With proper water quaity and filtration no/very little supliments are required, except for food and occational calicium is all that is really ever needed.

    If you cant do this- Crocea would be much better for you. IMHO

    It is not possible for it to be 2 55 watt bulbs. Unless your tank is the length of a 55 gallon and the bulbs are 54 watts each, which I highly doubt. lol Do some rechecking on this. Your standard 54w bulb is 48".
    I have never heard of a 55 watt t5 in aquarium use.
