I have been wanting to get a clam and I am thinking a derasa is the way to go. I understand they get large it will be going into a 125. My question is I plan to have it in low nutrient because an sps dominate tank is my goal, will this cause any problems for it I know they like some nutrients on the water. Also, any thoughts or advice would be great. Not set on a derasa just hear they are the hardiest. Just rolling ideas around here don't plan on getting it next week or anything. I have two radions over my tank for light.
