Light for Clams
 

Would this light be enough for clams in a 18" tall tank?

For some types okay.

Different light needs for different clams and also some species look a lot better if viewed from above so placing high on the rock takes away for some.

Lots of clam info here:http://www.clamsdirect.com/forum/index.php

Clams, even the lower-light requiring species, will do better with more light. If you want to do clams, look into getting metal halides or you'll be very limited & the clams may go brown & not do well for you.

I wouldn't try keeping clams with anything other than metal halide. After all your trying to provide an enviroment that they can thrive in, you may get away with keeping a clam alive but, as Anthony said they will lack the lure that made you want a clam in the first place.

We have successfully kept a crocea clam(blue type) in a 20 gallon(16" tall) now for a year or more under pc's 65 watts X 2. The clam has vibrant colour and seems healthy. We placed it near the top of the tank for better light penetration.

The key word here is thrive...not survive. It is best to always use the word thrive other then survive. Cause really you want an environment where the creature can feel right at home(the ocean). If your clam shows no growth in a year then you are giving it just enough light to survive...this is not exactly what we reefers are aiming for is it??

Research before you buy. Think about what it really needs and not just want you want in your tank. Metal Halide is the way to go for this species.

I remember thinking my crocea was looking pretty good after six months of PC lighting. :wink:

So I took a picture of it. Then I found a picture I had taken when I bought it. :surprise: It had really lost color but without the comparison picture, I had not realized it.

With ours its just the opposite... I was looking at a picture of the clam I took a year ago and it had less color than it does now. ;)
