I’ve kept this fish for over a year in a 150-gallon tank. It’s very striking with its black and white markings. I’ve had to be careful with smaller fish, as it does nip occasionally. The tank needs to be dimly lit and has plenty of hiding spots. Feeding at night works well. Overall, a beautiful but demanding addition to a saltwater setup.

This fish is impressive in appearance and grows steadily. I made sure to keep it in a large tank with plenty of rock and caves. It’s semi-aggressive, so I removed a small shrimp that got nibbled. Feeding it meaty foods at night keeps it active and healthy.

The Painted Sweetlips looks great, but it’s not for beginners. I had to adjust lighting and feeding schedules. It does show interest in smaller tankmates, so I now keep it with larger, robust fish only. Still, it’s a unique and eye-catching species.
