Pinnatus Batfish

About this fish

The Pinnatus Batfish is a saltwater aquarium fish sold under the scientific name Platax pinnatus. It’s a distinctive reef-associated butterflyfish (family Chaetodontidae) known for its unusual look, making it a great choice for aquarists who want something different in a mature, well-managed marine setup. In practice, it’s a visually striking mid-to-larger tank fish that does best when fed an appropriate meaty diet and kept with tankmates that won’t be outcompeted or provoked.

Features:

• Unusual centerpiece-style fish for a home saltwater aquarium
• Do best in a mature, stable system before being added to reduce stress
• Feed a varied diet of quality frozen foods to support a more complete diet
• Plan tankmates carefully and consider that this fish is an active feeder
• Acclimate slowly when it arrives and allow quiet settling time
• Best results come from asking us about your specific setup and compatibility questions
