In this deep unknown lie many unusual creatures that have yet to be studied. Other species are able to survive in wider temperature ranges. This is the opposite of mammals, for example, which rely on internal processes to maintain a constant body temperature.

Fishes are aquatic; cold blooded vertebrates. The fish contains head containing a brain and sensory organs, a trunk with a muscular wall surrounding a cavity with the internal organs and a muscular post-anal tail.

Freeze dried Tubifex worms, bloodworms, Daphnia, mosquito larva, brineshrimp and vegetation (such as boiled peas and lettuce) are good supplements for these fish. Fish like Trigger fish can swim backwards. The wild Goldfish are omnivores and eat plants, insects (such as mosquito larvae), zooplankton, detritus and small crustaceans. This characteristic fusiform shape is quite energy efficient for swimming. Unlike mammals, fish are cold-blooded (ectothermic).
