Victor Cameron –
I’ve had this butterflyfish for six months in a 100-gallon tank. It’s peaceful and active, and it’s adapted well to the environment. The coloration is vibrant and it’s a great addition to a community tank with non-aggressive fish.
Nicholas Mathis –
The fish looks beautiful and stays calm. I’ve maintained stable water parameters and it’s thriving. It’s not for small tanks, but in a properly sized setup, it’s a stunning species.
Melanie Sharp –
It’s a bit shy at first, but after a few weeks it started swimming around more. I’m not sure about compatibility with some other fish, so I kept it with only non-aggressive species.
