Cichlids are cute little fish with a vicious appetite.
- Cichlids are a family of fish, of small to medium size, with in excess of 1600 discovered species out of the estimated 2000 to 3000 in total.
- The scientific name of a cichlid is Cichlidae, and it is from the suborder Labroidei, the suborder that also includes wrasses, surfperches and damselfish, among others.
- Cichlids are found in freshwater regions in many countries across the globe, and they are native primarily to South America, southern North America and Africa, and some are also found in certain areas in Asia.
- The size of cichlids ranges quite widely among species, from 2.5 to 100 centimetres (1 to 39.4 inches).
- Cichlids are popularly kept in aquariums as pets, with many different hybrids bred specifically for the pet industry.
- The diet of cichlids, depending on the species, consists primarily of plants, fish – even from the same family, algae, parasites and insect larvae.
- Cichlids are often fished as a sport, and some species are mass-bred for commercial reasons, commonly for food or as pets.
- The colours of cichlids range from black, yellow, orange, green, blue, red, silver or white, and they are commonly patterned in their colouring.
- An average of 200 eggs is produced by a female cichlid at one time, and the fry are generally cared for by both parents until the babies are capable of swimming alone.
- Cichlids typically live to be 5 to 60 years of age; and fellow fish, eels, birds and humans are common predators.
Don’t get a common barbel in your face.
- Common barbels are a species of smaller-sized fish mainly native to various countries in Europe.
- The scientific name of a common barbel is Barbus barbus, and it is from the family Cyprinidae, the family of carps and minnows.
- ‘Common barbels’ are also known as ‘barbels’, the broad name of the genus; and ‘pigfish’, from an English legend.
- Common barbels inhabit freshwater locations such as rivers and lakes, and they are generally found in the water, close to the stony ground.
- Common barbels grow to be 10 to 120 centimetres (4 to 47 inches) in length and weigh 1 to 12 kilograms (2 to 26 pounds).
- The diet of common barbels consists primarily of fish, algae, larvae of insects and crustaceans.
- The number of eggs produced by common barbels at one time is said to be in the thousands, for every kilogram of fish weight, due to the large quantity that are initially eaten by other water creatures.
- Common barbels have a lifespan of up to 15 years, and they are commonly fished for sport, commercially grown for food, and used in the pet industry.
- Common barbels can feature numerous small black spots, and they are generally coloured mainly brown or grey, with the addition of silver, white, and pink colours.
- Although classified as least concerned, both pollution and habitat loss threaten some common barbel populations.
A snappy Australasian snapper.
- Australasian snappers are fish native to the ocean near Australia, China, Indonesia, Japan, Philippines, Taiwan and New Zealand.
- ‘Australasian snappers’ are also known as ‘silver seabreams’, ‘snappers’, ‘cocknies’, ‘pinkies’, ‘queens’, ‘schnappers’ and ‘ruggers’.
- The scientific name of an Australasian snapper is Pagrus auratus, from the family Sparidae, the family of sea bream, and despite its common name, it is not technically a snapper.
- Australasian snappers can be found in waters near the coast, around underwater rocky landscapes, among reefs, and in depths of up to 200 metres (656 feet).
- The lifespan of Australasian snappers can reach from 40 to 54 years; and young females may develop into males by adulthoood, although this is not common in some areas.
- Australasian snappers generally grow between 40 to 130 centimetres (16 to 51 inches) in length, and weigh between 10 to 20 kilograms (22 to 44 pounds).
- Australasian snappers are among the most commonly eaten fish by humans in countries where they are found nearby, such as Australia.
- The diet of Australasian snappers generally consists of crabs, shrimp, starfish, other fish, sea urchins and shellfish.
- Australasian snappers can have scales ranging from red, pink, grey, silver or gold in colour, and mature adults develop an obvious hump on the top of their head.
- Australasian snappers often cannot be legally caught for human consumption if they are less than 35 centimetres (14 inches) in length; and this is to prevent over-fishing so as not to damage the population of fish.
