How to choose fish for a tropical fish tank

This film will show you how to select fish for a tropical aquarium. It will help you decide which types to choose and how many to keep in your tank. The type and number of fish you can keep will depend on the size of your tank. An easy formula for calculating how many fish you can keep is to multiply the length of the tank by the width to get the surface area, and then divide this number by 30. There are a vast number of tropical fish species available for keeping in aquariums. Some of the most popular species include: Tetras, Guppies, Platys, Gouramis, Siamese Fighting Fish, and of course the iconic Angelfish. Some of the larger and more specialized varieties include Pufferfish, Arowanas and Piranhas, which have a fearsome reputation. When placing aquarium fish of different species in the same tank together, known as a community tank, it is important to choose species that are known to be compatible and will not eat each other. Well chosen fish will live together in harmony and will create a stunning aquarium display.
