Chaetodon collare
The Pakistan Butterfly, *Chaetodon collare*, is a beautiful and relatively hardy butterflyfish, making it a good choice for the beginner marine aquarist. Its body is primarily a silvery-white with a distinctive broad, dark band running vertically through the eye. A prominent white band is located just behind this dark band, and the posterior part of the body is often a dusky yellow or brown. The fins are typically edged in yellow or white.
A minimum tank size of 125 gallons is recommended for the Pakistan Butterfly to provide ample swimming space and stable water parameters. They are generally peaceful but can be territorial towards other butterflyfish or similar-shaped species. They are best kept singly or in a very large aquarium with other non-aggressive fish. While they may nip at some corals, they are generally considered more reef-safe than many other butterflyfish species, especially if well-fed.
In the aquarium, the Pakistan Butterfly will accept a varied diet of high-quality marine flake food, pellet food, frozen mysis shrimp, enriched brine shrimp, and chopped seafood. Offering a diverse diet is crucial for their long-term health and vibrant coloration. They typically reach a maximum size of around 6 inches in captivity.
