Hey guys i bought a 6inch Squamosa Clam about a week ago. He has been pretty off and on and seems to not be very happy. He resonds well to light and shadows, there are no pests, im assuming my water quality is great because my reef is thriving in both Fish and Coral health. My tank size and lights are listed in my signature. I currently have him sitting on a old clam shell in the sand like i use to do when selling them in the store. He keeps flipping off of it and moving. Not sure if hes trying to get away from my light or search for more. Ive done everything with my tank with good success except a clam because i have a long nose butterfly that would eat all my other attempts. Few years later i decided to try again and get a larger size in hopes the butterfly would leave it alone and sure enough he is. No only if i can get the **** thing happy!!
