After months of research, I finally added the Sweetlips to my 125-gallon reef tank. It has settled in well and shows active behavior without attacking other fish. The size is as described, and it’s a striking addition to the display. Only recommend for experienced aquarists with proper tank conditions.

The fish arrived healthy and was properly sized. It’s not aggressive, but it does require a large tank and stable water parameters. I’ve had to monitor its interactions closely with other fish, but overall it’s a good fit for a reef setup.

I expected more activity, but the Sweetlips is calm and doesn’t cause issues. It’s a bit shy at first, but after a few weeks it started exploring. Not for small tanks or new hobbyists. Water quality must be excellent.
