In the Guangdong Province of China, the latter species, as well as C. bengalensis, C. guerini, C. limbatus, C. sugillatus, C. tripunctatus, and probably also the well-known Great diving beetle (D. marginalis) are bred for human consumption, though as they are cumbersome to raise due to their carnivorous habit and have a fairly bland (though apparently not offensive) taste and little meat, this is decreasing. Although not considered particularly fierce, adults have been observed working as a group and attacking much larger vertebrates such as tadpoles. I'm not real sure though since I'm not really a big insect person. When still in larval form, the beetles vary in size from about 1 to 5 cm (0.5 to 2.0 in).

What I need to know specifically is- Is there a possibility of aggression toward the much larger pickerel?- Do these actually eat fish, or would I need to provide insect larvae, snails, grass shrimp or something else?- Do I need to be careful about identifying a target species, or do all vicious-looking beetles in the area fill a similar niche?
