Zoster Butterflyfish
A bold black-and-white butterflyfish, dark at the front and rear with a broad white band across the middle. Unusually for the family, a genuinely reef-safe planktivore.
Feeding
A planktivore rather than a coral feeder, which is what makes it reef safe. Frozen mysis, enriched brine shrimp and marine pellets, two or three times daily.
Compatibility
Reef safe – feeds from the water column and leaves corals alone. Peaceful, and best kept in a group of three or more.
Behaviour and personality
Shoals in open water above the rockwork, feeding from the current rather than picking at rock.
Before you buy
One of very few reef-safe butterflyfish, and much easier to feed than the coral-eating species. Keep in a group and provide open swimming space.

The Zoster Butterflyfish is a beautiful addition to my reef tank. It doesn’t touch the corals and is very active in the open water. I feed it mysis and brine shrimp daily and it thrives. The group behavior is natural and peaceful.

I was worried about introducing a butterflyfish to a reef tank, but this one is truly reef-safe. It swims in the open water and only eats from the current. Feeding is simple and the fish looks vibrant.

After adding this fish to my tank, I noticed the water movement is more dynamic. It’s a peaceful fish that doesn’t stress other inhabitants. I keep it with two others and they form a nice shoal.
