The Triangle Butterflyfish is a beautiful addition to my 60-gallon tank. It’s peaceful and active, and it blends well with other fish. I’ve had it for three months and it’s thriving. Easy to care for once the tank is properly set up.

Great color and movement. I noticed it’s more active during the day and stays near the mid-level of the tank. It’s not aggressive and doesn’t bother other fish. Just make sure the tank is large enough.

Perfect for intermediate aquarists. The fish is vibrant and stays calm. I appreciate that it doesn’t eat corals or invertebrates. It’s a reliable and attractive species.
