The Golden Semilarvatus Butterflyfish, also known as the Golden Butterflyfish or Red-lined Butterflyfish, is bright yellow with a series of closely-spaced orange stripes on the sides, and a dark blue-gray patch behind the eyes.
A 125 gallon or larger aquarium with peaceful tank mates provides a good environment. The Golden Semilarvatus Butterflyfish can be kept in pairs or small groups in a larger aquarium.
A diet of vitamin-enriched live foods or fresh clams may be needed in the beginning. Provide herbivore preparations once the fish begins eating.
Approximate Purchase Size: Small: 1-1/2" to 2-1/4"; Medium: 2-1/4" to 3-1/2"; Large: 3-1/2" to 4-1/2"

A spectacular fish. One of the few that can be kept in groups. I have four in 180 gallon tank and they school constantly. Beauty and grace are on display! Their "blue masks" are unique.
I have a pair of these gorgeous fish, Sunshine and Buttercup. Very active and colorful. They do require pristine water conditions though. For a few weeks, I'd gotton lazy on performing my regular water changes. And when the water is old and nitrates climb a bit, they seem to sulk around, don't eat as boldly, and they both get white spots on their fins which appear to be ich, but it is not. A large water change clears it right up within a couple of hours, and they're back to their lively selves. I saw the connection between the water conditions and their behavior. So I've learned my lesson, and have returned back to my regular water change routine. They deserve the best care; these are certainly not for the lazy fish keeper!
They adore grazing on nori sheets throughout the day, and really love meaty fare such as clam, mysis shrimp and squid. Very friendly towards tankmates.
