hey all, i just picked up a 5-6 inch crocea yesterday from my LFS for $50with my discount since i used to work there..anyways, its pretty decent size and i want to know where is the best place to put them? i have been seeing people saying that it is great to have them up in the rocks, i have mine at the bottom of my 90 gallon, but there is 400 watt MH's above it.."it was under 250 watts at the pet store" but that should take care of it, correct? its my first clam..just making sure i am doing things properly. any other suggestions or help on caring for this properly is appreciated.it burrowed into the sand and kindave tilted itself at an angle but not much, its open and looking great. im assuming its doing just fine?
