General: The Valentini Saddleback Puffer (Diodon holocanthus) naturally occupy the shallow lagoons surrounding the eastern shores of Africa, and Indonesia. The Valentini Saddleback Puffer will reach a length of over four inches, is not considered to be "reef safe", and should only be kept in an aquarium larger than 55 gallons. This Puffer is typically an opportunistic predator, targeting slower marine fish species, as well as crustaceans, anthozoans, and mullusks. This Puffer may be used to "cycle" a new aquarium, although it is important to consider this semi-aggressive fish being the final addition (for territorial purposes). The Valentini Saddleback Puffer should not be kept with another, as they will typically become aggressive towards each other. When transporting the Valentini Saddlback Puffer, it is critical to ensure the fish cannot directly inhale excessive amounts of atmospheric oxygen. When this occurs, Valentini Saddleback Puffers often have a difficult time expelling the oxygen. It is often best to transport this fish inside of a bucket, as opposed to with the use of a net.
Despite being for a more advanced aquarist, the caregiver will likely be rewarded with the Puffer acting as a true companion, behaving in a very attentive manner when greeted.

Aquarium Diet: The Valentini Saddleback Puffer (Canthigaster valentini) is naturally an omnivore, primarily preying upon benthal (bottom dwelling) invertebrates such as coral, mussels, and crustaceans. The Porcupine Puffer may also be found grazing upon various algal species. It is often ideal to provide a balanced diet for omnivorous Puffers containing an algae species such as Spirulina, and chlorella.
