The Largenose Boxfish is a beautiful addition to my aquarium. It’s active but not aggressive and enjoys the hiding spots I provided. Water parameters stayed stable after setting up the tank properly. I recommend it for those with a moderate to advanced setup.

It looks stunning in the tank. I’ve had it for three months and it’s adapted well. Feeding it a mix of mysis and flakes keeps it healthy. Needs a large tank though, so make sure you plan accordingly.
