What Food Does the Yellow Cusk Eel Require in Captivity:

Feeding the Yellow Cusk Eel in captivity can be challenging due to their secretive and burrowing nature. Their diet should primarily consist of:

  • Live or frozen food: Offer small or frozen prey such as brine shrimp, mysis shrimp, and finely chopped seafood. These foods are more likely to entice their feeding response.
  • Occasional pellets: While Yellow Cusk Eels may not readily accept pellets or dry foods, some individuals can be trained to eat them over time. However, it's essential to ensure they receive a varied diet.
