This sweetlips has been in my 125-gallon reef tank for six months. It’s active and doesn’t harm the corals. I’ve had to watch its behavior closely, but it’s stable. A good choice for experienced aquarists.

The fish arrived healthy and has adapted well. It’s semi-aggressive, so I keep it in a well-structured tank with plenty of hiding spots. Not for beginners, but rewarding to care for.
Nicola Newman –
It’s a large fish and takes time to settle. I’m used to reef fish, so it’s manageable. I noticed it occasionally nips at smaller invertebrates, so I’ve added more barriers.
