Crocea Clams and Compact Fluorescents

[Domboski]

I know I have seen this topic somewhere but could not find it. I was thinking of moving my Crocea clam from a metal halide (150 watt) to a tank that is 12 inches high with a coralife 4*65 watt compact fluorescents.

Is this ok or will the clam suffer?

I think it'll be fine - make sure it is about 4" from the water surface

All other factors being the same, the clam will do better under the halides. It will live, but you'll probably notice a decrease in color and a drop off in growth rate. How big is the tank you're putting it in?

 

[Domboski]

40 Gallon Long. It is in a 20 gallon hex. It has been under the halides about 10 months.

A few years ago, I kept croceas under VHOs for about a year and moved them to halides and noticed much better color and faster growth in just a few months. Why do you want to move it?

I have had a crocea about 4-6" under my PCs for about a year- looks healthy and there is shell growth, but I know it would probably do even better under MH. I wouldn't put it any further from the PCs than that though...

I am trying to move all of my coral into my 120 and 40 gallon reefs. I don't have to move him I just thought he would have more room. I will eventually have halids over the 40 gallon long so maybe I should wait. If he can live ok under the VHOs for a 2-4 weeks than I will move him. Electricity bill is the main factor. 3 reef tanks = $$ in Con Ed's Pocket

Yeah, it'll be fine under VHOs for a few weeks. It's really more of an issue with long-term care, where you'll really notice the differences.
