The Maxima clam has transformed my reef tank. Its colors are stunning under blue lighting, especially when the mantle expands. I’ve maintained stable water parameters and provide consistent lighting. It’s a beautiful centerpiece that adds depth and vibrancy to the display.

I bought this as a centerpiece and it’s been thriving for over six months. The color shifts are impressive, especially in the evening light. It’s a bit large for a small tank, so make sure your setup has enough space and strong lighting.

The clam attaches well to a solid rock and grows steadily. I noticed the iridescence under blue LEDs, which is truly captivating. Water quality has to be excellent, but once that’s stable, it’s a rewarding addition.
