Do sun catfish eat feeder fish?

Sun catfish (Platydoras costatus) are opportunistic omnivores and their diet mainly comprises small living and dead fish, plant matter, algae, aquatic insects, worms, crustaceans, snails, and zooplankton. They may consume feeder fish in aquariums if given, but these should not form a staple diet as such feeder fish may introduce unwanted diseases. In their natural habitat, they typically feed on a wide variety of available food sources rather than just focusing on single prey items like feeder fish.
