Due to their distinctive shape and bright colors, discus are popular as freshwater aquarium fish. They are sometimes referred to as pompadour fish.
Many years ago, when I first saw parrots and learned about their unnatural origins, I was horrified. I was an outspoken critic of the parrot cichlid and hated them without ever knowing them. Since then, I've placed many parrot cichlids into tanks located in hospitals, daycares, schools, nursing homes, and the like. There is no other fish that gets the level of positive attention these fish do—everyone is drawn to their bright color, their personality, and their outright cute shape. They're large, incredibly hardy, superbly colored, and not particularly aggressive, filling a niche among freshwater fish that is unmatched. As people become enamored with the parrot, they often ask “How can I keep one?” and soon join the ranks of aquarists. Many eventually move onto all sorts of aquarium keeping. At the end of the day, that's the important thing: They get people interested in the aquarium. Give the parrot a chance; you won't regret it.
Middle-dwelling fish could be most striking and be stocked with larger colorful fish and a mixture of schooling fish. Schooling fish are clearly happiest when they are with their mates and you need to have around six. Examples of schooling fish include Rainbow fish and Tetras. Rainbow fish are easy to look after and their amazing shimmering colorations change when light reflects off these fish. Neon Tetras choose to swim or remain suspended in schools to create a magnificent array of color. All types of Platies and Guppies are first-rate for middle-dwelling fish. They are both easy care fish and come in many bright color variations which add excitement and brilliance to freshwater fish tanks. For something slightly larger, Swordtails are easy to look after and have wonderfully diverse fin and color varieties. Mollies add drama and contrast to any aquarium but require a moderate level of care. The following small Gouramis are of a peaceful temperament and easy to tend: Neon Blue Dwarf, Sparkling Gourami and Dwarf Gouramis. Angels are a striking fish to include in your aquarium but bear in mind they are semi-aggressive and growing to 6 inches they also require at least a 30 gallon tank. For a larger tank (50 gallons), Cichlids are an option but many can display signs of aggression. Examples of peaceful ones are Albino Kribensis Cichlid, Acei Cichlid and Brichardi Cichlid. Of course, the Goldfish remains the most popular freshwater fish and comes in many varieties with amazing features and color patterns.
