What do ghost catfish eat and how can their diet be best maintained in a home aquarium?

Ghost catfish are omnivores and primarily eat small insects, worms, and plant matter in their natural habitat. In a home aquarium, their diet can be best maintained by feeding them a variety of foods such as sinking pellets, frozen or live foods like bloodworms or brine shrimp, and occasional vegetables like blanched zucchini or cucumber. It is important to provide a balanced diet to ensure their health and well-being.
