My species/animal is a fish — the Foureye Butterflyfish (Chaetodon capistratus). It is a peaceful species that is reef-safe with caution, admired for its silver-white body adorned with thin, dark vertical lines, a distinctive dark eyespot ringed in white near the tail (used to confuse predators), and an elegant teardrop-shaped body. Its subtle beauty and unique markings make it a favorite among marine enthusiasts.
Males typically look nearly identical to females, with no significant external differences, though males may exhibit territorial or courtship behaviors during breeding. Females/juveniles share the same pattern and coloration, though juveniles may have a slightly more prominent eyespot and appear more translucent until maturity.
They reach about 6 inches in adult size and should be housed in aquariums of at least 70 gallons.
Provide plenty of live rock for grazing and hiding spots, a soft sandbed, and open swimming space, stable water parameters (salinity ~1.020–1.025, temp ~72–79°F, pH ~8.1–8.4), and a secure lid since many species are prone to jumping.
Diet should consist of frozen mysis shrimp, brine shrimp, copepods, marine algae, finely chopped seafood, sponge-based frozen foods, and occasionally high-quality pellets and flakes, and with proper care this fish makes a standout addition to the aquarium.
