Read these interesting curious wormfish facts to learn about this mixed breed.

The curious wormfish is a unique and intriguing reef fish possessing an extended eel-like body with longitudinal orange and blue stripes. They are susceptible to low water quality as well as handling and transportation stress.

Keep this species in a 30 gal (136.3 L) aquarium with a fine sandy substrate for burrowing at night. The tank must have a tight-fitting lid with no gaps, as leaping is the most common cause of death in captivity for curious wormfish. They're enigmatic, and they're difficult to feed, so give them meaty meals such as Mysis shrimp.

To attract picky eaters, use enhanced live adult brine shrimp. Choose tank mates that are tiny and calm and will not hurt or frighten them.
