Fauna

Siamese fighting fish

The Siamese fighting fish, commonly known as the betta, is a popular fish in the aquarium trade. Bettas are a member of the gourami family and are known to be highly territorial. Males in particular are prone to high levels of aggression and will attack each other if housed in the same tank. If there is no means of escape, this will usually result in the death of one or both of the fish. Female bettas can also become territorial towards each other if they are housed in too small of an aquarium. It is typically not recommended to keep male and female bettas together, except temporarily for breeding purposes which should always be undertaken with caution.

The rainbow trout is a trout and species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to fresh water to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.

They are highly adaptable and thrive in many different environmental and ecological conditions. Male guppies, which are smaller than females, have ornamental caudal and dorsal fins. Wild guppies generally feed on a variety of food sources, including benthic algae and aquatic insect larvae. Guppies are used as a model organism in the fields of ecology, evolution, and behavioural studies.

Fauna

Basa fish

Basa is a species of catfish in the family Pangasiidae. Basa are native to the Mekong and Chao Phraya basins in Indochina. These fish are important food fish with an international market. They are often labelled in North America and Australia as "basa fish", "swai", or "bocourti". In the UK all species of Pangasius may legally be described as "river cobbler", "cobbler", "basa", "pangasius", "panga", or any of these with the addition of "catfish". In the rest of Europe, these fish are commonly marketed as "pangasius" or "panga". Other related shark catfish may occasionally be incorrectly labeled as basa fish, including P. hypophthalmus and P. pangasius.
