Jason Morrison –
I’ve kept this snapper in a 150-gallon reef tank for over a year. It’s peaceful and doesn’t bother the corals. Only suitable for expert aquarists due to its size and care needs. A great addition to a mature reef setup.

The fish arrived healthy and has been active since setup. It’s not aggressive and coexists well with other reef species. Requires a large tank and stable water conditions, which I have.

After researching several species, this one fits perfectly in my large tank. It’s calm, grows steadily, and doesn’t eat corals. Definitely recommended for experienced reef keepers.
