Saltwater Fish

Tropical fish include fish found in tropical environments around the world, including both freshwater and saltwater species. Fishkeepers often use the term tropical fish to refer only those requiring fresh water, with saltwater tropical fish referred to as marine fish.

Saltwater fish from coral reefs are famous for their bright coloration with some fish being fluorescent.

Angelfish

These big beauties are luridly coloured and very interesting to watch, but not for the faint hearted aquarist. They need large aquariums and should not be kept in groups. Two angels might be kept in the same aquarium provided it is a large aquarium, they are properly acclimated as juveniles, and they are have very different colouring and body shape. However, because all Angelfish have essentially the same diet, mixing them is a feat that should be left to only advanced keepers. None are reef safe, and a potential owner should be aware that they need to have plenty of vegetable matter in their diet. They undergo major changes in colouration while maturing, and unless specified given descriptions are for adult specimens.
