Crocea & lighting needs
okay... general question for all of you crocea owners.
what kind of lights do you have, and how close to the light do you have the clam ?
i'm wondering if i could attempt one or if i should not bother.
FWIW, i have 8x54W T5 TEK fixture, ~6" above the water surface.
i will be setting up a new tank sometime this year with a smaller (T5) fixture, tank will be more shallow, and lights will be closer to the surface.
J.

we got our first clam this weekend, and that answered my questions.

I've got a couple croceas with 7 T5 bulbs. They're both on the bottom, but I think they'd be a bit happier a little higher up. And since I'm overdriving my bulbs, you're probably best sticking them about half-way up or higher in your rocks. But, you should be able to keep one with out too much trouble.

I kept them under 2X175MH and 2X90W actinic VHO, half way up the rock. It worked fine for me. I'm so not up on T5 technology, so couldn't help you there.

3 x 250 MH and 8 T-5 actinics, halfway up the tank.
You don't have to go this strong, though.

You will be fine with the T5's. Do they have individual reflectors?
I have kept croceas under 250MH from the sand to up high in the rock. I currently have them on the sand in my 140 under 400W MH. PAR on my sand bed is about 150.

I've had two croceas and a derasa kept under 260 watts of PC lighting. All three did great! The two croceas I kept a little bit higher up on the rocks which made removing them next to impossible. A little while back I upgraded to T-5's and they did even better.
