The **Jackknife Fish** is a fascinating species with a distinctive shape. Its elongated fins give it the appearance of a jackknife, which is how it got its name. This fish is primarily white with bold black vertical stripes.

Reaching up to 10 inches in length, **Jackknife Fish** require a minimum tank size of 120 gallons. They are peaceful and generally do not disturb other fish or most corals. However, they do consume invertebrates, making them unsuitable for reef aquariums.

In larger fish-only tanks, the **Jackknife Fish** can be a stunning addition, especially when kept in small groups. To minimize aggression, introduce multiple **Jackknife Fish** simultaneously. They thrive in environments with ample live rock and sand, where they forage for invertebrates between feedings. Being peaceful, they may retreat to rock formations if threatened.

As carnivores, **Jackknife Fish** need a diet rich in meaty foods. Mysis and brine shrimp, high-quality frozen foods, and small pieces of fresh seafood will keep them healthy and content.
