Four Spot Butterflyfish


The Four Spot Butterfly Fish has a dark yellow and brown body with two white patches on each side.The Four Spot Butterfly can sometimes be difficult to keep in an aquarium setting for a beginner aquarist. They require at least 50 gallons, can nibble on certain coral species, and can become territorial with smaller fish and other butterfly species. Further, the Four Spot Butterfly will pick on sessile invertebrates and even small hermits and crabs if not fed well.The aquarium should be able to hold a minimum of 55 gallons with a temperature range between 72 - 80 degrees Fahrenheit and a pH level of about 8.1 - 8.4. Good neighbor, easy to keep, and even good in reef tanks.
