🐠 Dog Faced Pufferfish (Spotted) (Arothron nigropunctatus)
One of the Most Personable Puffers • A Dog-Like Face and Personality • Grey-Brown With Scattered Black Spots
 
📋 The Dog Faced Pufferfish, also known as the Blackspotted Puffer or Arothron Dog Face Puffer, gets its endearing name from a face shape reminiscent of a dog. This spotted variant shows a grey-to-brown body scattered with black spots, though colouring and pattern vary considerably between individuals, and some rare specimens even appear all-black, dalmatian-patterned, or with a yellow underside.
It's native to a wide range across the Indo-Pacific, where it inhabits coral reefs and lagoons, and it's one of the most personable, interactive puffers in the aquarium trade: often shy at first, but becoming bold enough to recognise its keeper and eagerly anticipate feeding time. An interesting anatomical detail: it lacks pelvic fins, manoeuvring with its pectoral, dorsal, and anal fins, and its teeth are fused into a beak-like structure that grows continuously and needs hard-shelled foods to wear down naturally. It isn't reef safe, and will destroy corals, crabs, and snails.
Like all pufferfish, it carries tetrodotoxin, which makes it toxic if eaten, so never eat a pufferfish, and wash your hands after tank maintenance. Never let it inflate out of water, and use a rigid container and not a net for transfers, since forced inflation can be stressful or even fatal.
