For captive keeping, what specific protein source must form the basis of a diving beetle's diet?
Answer
Live or freshly killed animal protein
Maintaining a captive diving beetle requires management focused on its innate predatory nature. For these obligate carnivores, the diet must fundamentally consist of animal protein that is either currently alive or has been very recently killed. Specific examples suitable for this requirement include earthworms, small feeder fish like guppies, or bloodworms. Relying on processed food pellets designed for bottom-feeding fish is insufficient because it fails to provide the necessary nutritional profile or the crucial behavioral stimulation derived from actively hunting mobile prey, which is integral to their well-being.
