The Citron Butterflyfish is vibrant and active in my 55-gallon tank. It has adapted well to the reef environment and shows no signs of aggression toward other fish. A beautiful addition to a coral tank.

I’ve had this fish for three months now. It’s colorful and stays near the surface, which makes it easy to spot. I did notice it occasionally nips at smaller invertebrates, but overall it’s a good fit for my setup.

Great color and movement. The fish is active and seems healthy. I appreciate that it’s reef-safe and doesn’t damage corals. Only needed a bit of hiding space initially, but it’s now thriving.
