Mulleri Butterflyfish – LiveAquaria
The Mulleri Butterflyfish originates from the reefs of Australia and has a long, narrow nose and mouth used for hunting into crevices and holes for food. It features black vertical bands against a silver background, with a rust coloration towards the backside of the fish. An eyespot on the dorsal fin is used to confuse predators about the fish’s direction.
It is best suited for very large reef tanks or peaceful community aquariums. The fish should be kept singly, not with other butterflyfish or conspecifics, and should not be housed with stress-inducing species. Caution is advised when keeping in reef environments, as they may feed on invertebrates such as anemones and feather dusters.

The Mulleri Butterflyfish is a striking addition to my reef tank. Its coloration and behavior are quite unique. I’ve kept it alone in a large tank and it’s active without causing issues with other fish. I did notice it occasionally nibbled on a feather duster, so I’ve moved it to a safer area. Overall, a beautiful and interesting species.

I was cautious about adding this fish due to the invertebrate risk, but it’s been peaceful in my 120-gallon tank. It doesn’t eat much and stays in one area. I’ve kept it alone and it’s not aggressive. Just make sure to monitor invertebrates closely.

The fish looks exactly as described—silver with black bands and a rust back. It’s very active and uses its eyespot to avoid predators. I’ve kept it in a large reef tank with no issues so far. It’s a great visual centerpiece.
