My lfs got a big shipment in of scallops. They are gorgeous! They told me I could put one in my tank now. I know better. But after looking at them I think I will eventually want one. How difficult are they to keep?\r\n\r\nWhat about clams? \r\n\r\nI know they need really good lighting and I am Pretty sure they filter feed. \r\n\r\nAre muscles at like the 1 year mark? Or can you try at around 6 months like corals?
