It is highly recommended that if you choose to include any of these fish in your aquarium, that you make them either the only fish or put them in an aquarium with a small community of peaceful fish that will not stress the Boxfish out. Boxfish need tanks of at least 75 gallons or more depending on their size. They prefer water between 72-78˚F with a pH of 8.1-8.4.
Boxfish are incredibly picky eaters and it is important that you meet their nutritional needs and meal preferences as a dead Boxfish can kill an entire aquarium. When first introducing your fish to its new home, it is important that you feed it fresh shrimp. Boxfish are omnivores, but they require foods that sink to the bottom of the tank. Do not feed foods that float! If your Boxfish is required to eat floating foods, they may gulp air that will affect their balance and buoyancy. In addition, these are slow eating fish and cannot be kept with other fish that will steal food as they will not get enough to eat. Feed weed sheets or algae wafers to meet their vegetation requirements and foods such as shrimp, crab meat, fish meat or clam meat for their protein requirements.
