I added a Squamosa Clam to my reef tank and it has been thriving. The blue shell stands out well among the coral. It’s active and seems to be using the scales for shelter. I’ve noticed small crabs hiding near it too. The lighting is strong, which matches the care instructions.

The clam looks beautiful and fits well in my Acropora setup. It’s been a few months now and it’s still healthy. I keep the tank well-lit, and it seems to be doing fine. A bit larger than expected after a few weeks.

Great addition to my aquarium. The blue color and scale pattern are striking. It anchors itself to the coral and doesn’t seem to move much. I appreciate how it provides a natural habitat for small invertebrates.
