Its a 46 gallon tank with a coralife lunar aqualight, 1 (96 watt actinic) and 1 (96 watt 10000k) bulbls. I believe the clam is a Crocea. I dont know for sure though. When I first got the clam it wasnt in the best shape, but the price was right. It was solid brown then, but now a little blue is starting to come out on it.
