I bought this clam for my mid-sized reef tank. It’s been two months now and it’s doing well. The color is vibrant and the pattern is unique. I keep it on a solid rock and make sure the lighting is consistent. It’s a bit large, so I had to adjust the placement carefully.

This clam is a true showstopper. The iridescence under blue light is incredible. I’ve noticed it’s photosynthetic, so it helps with the tank’s overall health. I’m happy with the investment and the visual impact it brings to the tank.
