Received the blue maxima clam and it’s stunning. The electric blue color is vibrant and stands out in the tank. It attached well to the rock and seems healthy after a few weeks. Easy to maintain and peaceful in the community.

The clam arrived as described, with a nice electric blue hue. It’s a beautiful addition to the reef. I placed it on a flat rock and it attached quickly. It doesn’t seem to interfere with other inhabitants.
