Ruth Gibson –
The female Lamarck angelfish has been thriving in my 120-gallon reef tank for six months. It’s calm and doesn’t bother other fish. The size is within the expected range, and it looks healthy and active.

I added this angelfish to my tank after researching compatible species. It’s peaceful and has not shown any aggressive behavior. The tank size is sufficient, and it blends well with the coral.

Great addition to a reef setup. The fish is active but not territorial. I appreciate that it’s reef-safe and doesn’t require constant attention.
