Tropical fish
Last updated
Freshwater tropical fish are more commonly kept than saltwater ones because fresh water is readily available.[1] Fish kept in heated aquariums are commonly referred to as tropical fish.[1] Freshwater species make up the majority of fish sold as tropical fish.[2]
Biology and range
The bright colors of tropical fish come from both pigmented cells and iridescent cells.[1] The most popular group of aquarium fish is tropical freshwater fish, due to their low cost and the simplicity of keeping them.[3] Because of extensive cross-breeding, some male flowerhorns are infertile.[3] Evaporation in saltwater aquariums means the water must be monitored to keep salinity at the correct level.[1]
What the specialist sources record
The Florida Tropical Fish Farms Association is a trade association of professional ornamental tropical fish and aquatic plant breeders.[4] The FTFFA states that the best tropical fish and plants come from Florida.[4] A flowerhorn care guide notes that clean, safe water promotes fish health and enhances color.[5] The same guide states that flowerhorns are large fish and release enough waste to raise ammonia levels substantially in a week or two.[5]
The guide recommends fish food with balanced amounts of color-enhancing pigments, with astaxanthin being the most widely used enhancer.[5] The guide advises that feeding blue dragon flowerhorns red-enhancing pellets can cause the fish to turn dark for months.[5] The FTFFA is the only active organization that devotes its entire efforts to supporting the professional, ethical, economic, and social aspects of the tropical fish industry.[4]
