Fish

The size and diversity of fish populations on Altoid is gigantic. Usually small, these fish tend for the most part to stay amongst the many clumps of underwater plans, both for protection and for the food to be found there in the form of algae. Others burrow in the mud. The larger fish tend to be carnivorous, feeding mostly on the small, numerous darters that abound in all Altoid's waterways. Fish are an important part of the diets of alligator snakes, bears, beatles and, as has been said, other fish. They are also the exclusive food of swimming birds. For the most part completely defenseless save for their speed and elusiveness, fish populations nevertheless remain constant in the face of heavy predation due to speed at and the numbers in which they spawn.

The main role of fish is to provide food for other species. Without them. many animals, especially Alligator Snakes, would be threatened with starvation, while the birds would unquestionably become extinct, thus removing another species that feeds the Alligator Snakes. The snakes in turn would be forced to subsist on frogs and rodents, and their numbers would be decimated. The normally huge amount of dead fish is the main source of nutrients for sub and semi-submarine plants, which would sicken without them and effect even more species.
