Shortnose Boxfish

(Rhynchostracion nasus)

Rhinesomus Trunkfish should be added first to large aquariums with ample open swim room as they are slow swimmers and become quite large. Provide rocky areas and a thick sand bed. Trunkfish might be slightlyly sensitive to aquarium lights when first added, monitor for light sensitivity. They may also be difficult to acclimate to aquarium diet, try offering live, enriched meaty foods such as Black Worms and Brine or Glass/Grass Shrimp. Trunkfish will also disturb sand bed by blowing it trying to uncover prey. They are constant grazers and have also been known to consume Cyanoacteria, Slime algae and other types of marcro and micro algaes. Provide a diet rich in meaty and algae based foods multiple times daily. Do not offer any floating foods as Trunkfish may ingest air which can cause buoyancy issues. They may release a toxin if excited or threatenedd. Always remove Trunkfish if being picked on or in poor health. Activated carbon will remove the toxins.

Shortnose Boxfish are also sometimes known as the Small Nosed Boxfish. They are occasionally seen in the aquarium brade but not as commonly available as some other marine fish species. The Shortnose Boxfish are white or gray with black spots. The Shortnose Boxfish can grow up to 12 inches in length.

We recommend a minimum aquarium size of 150 gallons or larger for this species.
