🐠 White Spotted Boxfish (Ostracion meleagris)
Marine Not-Reef-Safe Boxy-Shaped Fish • Striking Sexually Dimorphic Colouration With White Spots on Black or Blue • Genuinely Capable of Releasing a Fatal Toxin — Please Read Before Buying • Expert-Only Species
 
⚠️ Important Information — Please Read First
We want to be genuinely direct on this one. This species is genuinely notorious for releasing a powerful toxin called ostracitoxin (also known as pahutoxin) from its skin when highly stressed, which is genuinely capable of killing every other fish in the tank within minutes, and can affect a wide range of invertebrates too. This species should genuinely only be kept alone or as a single confirmed male-female pair, never with another male, as bickering can trigger toxin release. We genuinely recommend running activated carbon at all times as a precaution, and please keep foot traffic and sudden movements near the tank to an absolute minimum, as this species is genuinely quite easily stressed. This species is only appropriate for genuinely experienced aquarists prepared for this real, serious risk.
 
📋 The White Spotted Boxfish, also known as the Spotted Boxfish, Blue Boxfish, or Black Boxfish, displays genuinely striking sexual dimorphism — males have a vibrant blue body with a black cap and white-on-black or black-on-blue spots, while females are entirely black with white spots.
Native to the Indian and Pacific Oceans, from South Africa to Hawaii and the Galápagos Islands, this species inhabits coral reefs and rocky bottoms at depths of 1 to 30 metres.
We want to share a genuinely interesting fact: this species is always born female, with individuals changing sex to become males as they mature. This species is genuinely a relatively poor swimmer, relying on its toxin release as its primary defence rather than speed, and it's genuinely capable of jumping from open-topped tanks despite its less nimble locomotion. We want to be upfront: this species is not reef safe, and will genuinely nibble at tubeworms and other invertebrates.
