Clams under 4 bulb t 5 20 long

[zacheyp]

I know clams need a lot of light, is a 4 bulb t5 in my 20 long enough.

I hope so. I just bought a clam for my 20g and it's lit by a four bulb T5.

 

[zacheyp]

what type of clam did you buy, i really want one

I think Carey bought a Purple Maxima if I'm not mistaken... Maxima's and Crocea clamps require more light. Derasa clams are less light hogs, and I just picked up one last week.

I have it in a 54 gallon corner which is about 22" to the sandbed under 4-bulb T5, and so far he seems quite happy.

Don't see the pic... but the one I saw in your thread was beautiful!

Crocea and maxima are the most light demanding clams. The derasa and squamosa need less light but get way too big for a 20g.
