Some reports note that this fish may or may not be aggressive towards it's own kind,therefore, care should be taken when adding a new boxfish into a tank with an establishedboxfish. I cannot say for certain if this is true or not, but it was found in someof my research. Most hobbyists mention the Yellow Boxfish's gentle nature (even sofar as taking food from the hobbyists hand and being petted), but I couldn't find anyonehaving kept more than one in a tank so I cannot say if this is true or not.
Are they very difficult to care for compared to other boxfish

The Striped Burrfish or Spiny Boxfish is not the hardiest of the diodon family. They may be slow to start eating and like other puffers, they require special care and a special diet to stay healthy. Related Articles: Boxfishes, Puffers in General, Puffer Care and Information, Pufferfish ..

Boxfish area group of puffer like fishes and the group boxfish includes cowfish and trunkfish. They all have a squared body. Their bodies are enclosed by bones.

Boxfish can be found in a very large geographical area but most boxfish available in aquarium stores can be found in the Pacific Ocean in the wild. Some of the species available in the thread is however found in the Caribbean‘s.

Boxfish are best kept alone in an aquarium without other fish due to the fact that they if stressed can release a toxin that can kill other fish that comes in contact with the boxfish. Boxfish are very slow moving and easily stressed. There are also reports that they can release the toxin if they die and thereby poison the rest of the fish in the aquarium. I can not say whether dead boxfish always release toxin or if this only sometimes are the case. It is recommendable to make sure to remove dead fish immediately to minimize to toxin released.

It is however possible to keep boxfish with other fish in a community aquarium but you will than need to make sure to minimize the stress the boxfish are exposed to. It is in order to achieve this important to avoid keeping them with large or aggressive species. Don’t forget that some small species such as some goby species can be very aggressive and therefore isn’t suitable tank mates for boxfish.

There are a number of different boxfish species available in the aquarium trade. They are very interesting fish to keep if you can give them the care they require which can explain their growing popularity. One of the most popular species is Long-horned cowfish, Lactoria cornutus

Boxfish are best kept in larger aquariums with a small to moderate fish population in it. They prefer an aquarium with low to medium water circulation. The aquarium should be decorated so that the Boxfish can feel safe. This means that caves and other hiding places are highly recommended.

Different species of boxfish have different demands both in regards to water parameters and in regards to aquarium size. Some species of boxfish are very small while other grows considerable larger.

Quick Facts :: Cubicus Boxfish Care Level: Difficult Temperament: Semi-Aggressive Maximum Size: 18″ Minimum Tank Size: 125 Gallons Reef Compatible: Yes, with caution Water Conditions: 72-78° F, dKH 8-12, sg 1.020-1.025, pH 8.1-8.4 Diet: Omnivore Origin: Indo-Pacific to Southeast Atlantic Family: Ostraciidae Species: Boxfish Aquarium Type: Reef Compatible The Cubicus Boxfish […]The Blue Spotted Boxfish or Hawaiian Boxfish (Ostracion meleagris) is another favorite in the aquarium hobby. They grow only as large as 6 inches, so they can be easily kept in a smaller 55 gallon tank. This species is sexually dimorphic, so male and female are easily distinguished. The male is a spectacular bluish purple with golden spots. The female is typically a chocolate brown to black with white spots. They differ from cowfish by assuming different coloration, and lacking horns. In particular, they feed on algae, sponges and benthic invertebrates, including polychaete worms, small bivalves, tiny snails, and copepods. However, tunicates are considered to form the major portion of their diet. Their teeth are designed to scrape food, such as tunicates and sponges, off of hard substrate. These fish are active during the day when they hunt for food. At night, they rest by hovering above the substrate. Their care is is similar to the Longhorn cowfish, but they are much more difficult to keep. They asily succumb to a number of parasitic, fungal, and bacterial infections. They may also resist aquarium. It is best to keep live rock in the tank with this species. Unfortunately, this species is the most well-known for toxin release. They are considered poor swimmers and must rely on toxic body slime and their tough body shell for protection. Toxic episodes occur more frequently when Blue boxfish are kept with more than one of their own kind. It is imperative that two males of this species NOT be kept together. Surely bickering will result in toxin release. However, a male and female pair, or even 2 females may be kept together safely. Interestingly, these fish tend to ignore tank mates of unrelated species. Blue boxfish appreciate plenty of swimming room and some caves or crevices to hide behind. Like the Yellow Spotted boxfish, they are also known to jump out of tanks. These fish are distributed between Mexico to Japan, the Hawaiian Islands, the Great Barrier Reef, Northern California and Rapa.I do agree with jwreffner (here) about with proper care (Tank healthy, variety diet) & careful selection of tank mate, boxfish are not a problem to keep. I find them to be quite enjoyable to keep.
