I’ve had my Pinnatus Batfish for six months now. It’s a striking fish with a unique appearance. The tank is 180 gallons and well-lit, which matches its preference. Feeding it shrimp and algae weekly keeps it active and healthy. Just make sure there are no small fish or corals in the tank.

The fish arrived safely and looks great. I’ve set up a 150-gallon tank with strong lighting and a balanced diet. It’s not aggressive, but it does eat small invertebrates, so I removed any vulnerable species. Overall, a fascinating addition to the tank.

After reading the care guide, I made sure to provide a large tank and stable water conditions. The Pinnatus Batfish has adapted well and shows interest in both meaty foods and algae. It’s a beautiful species that adds a lot of visual appeal.
