Oyster Creek rainbow
This brilliantly coloured fish is probably the northern most duboulayi rainbow.
Doublayi Rainbow - Kangaroo Creek
This colour form of the Doublayi rainbow has been most popular in the aquarium hobby. It has the most intense colours of all the Doublai colour morphs.
The scales are almost all metallic blue, as show in the close-up view of their scales above.
These fish come from South East Queensland and can tolerate much lower temperatures than the species of rainbows from the far northern parts of Australia. In their natural habitat the water temperatures during winter can be as low as 15C in some of the smaller water holes.
This colour morph of the Australis is from south Alligator River in the Northern Territory. Although they will survive in our ponds during winter at temperatures below 15C, they much prefer to be kept at about 25C.
Coen River Rainbow
One of Queensland's popular trifasciatas, this fish comes from the Coen River which is in the central part of Cape York Peninsular. This fish usually displays a rich green colour. When in full display mode, (Usually when the morning sun hits the aquarium.), waves of colour roll across the body like waves. Once you see this display you will be hooked on this fish.
Wallaby Creek Rainbow
Wallaby Creek is in Far North Queensland, just south of Cook Town.
Salmon Red Rainbows - Incisus
It is common for males to have little colour until they have settled into a tank. Their colour, and the intensity, and the shade of the red can also vary considerably, depending on mood and lighting. Females can also have some colour variation. They can appear silver/grey to coppery, but never red.
Hidden Valley Rainbow
This beautiful, and rarely seen fish is so attractive it could easily have come from New Guinea. In the picture above it stands out even in the company of a Goyder, a Parkinsoni and a large Australis. Given our poor photographic skills, not a bad achievement!
This fish comes from the mountains between Townsville and Cairns. It appears to have two distinct colour forms. These pictures ore of the blue colour morph.
They are not a large growing rainbow, neither are they a dwarf form, but more an intermediate size. The largest fish we have seen is about 8cm.
Deep Water Creek Rainbow
This spectacular rainbow comes from a small creek system in Central Coastal Queensland. They will tolerate a wide temperature range from about 11c to over 40c. It has not yet been described but is classified as a Splendida. splendida. In appearance it looks like a red form of Inornata.

Davies Creek Rainbow
Pictured below, Davies Creek is in the mountains about 80 kilometres north west of Cairns, in far North Queensland.
Colosseum Creek rainbow
This is a new colour form of Melanotaenia duboulayi rainbow. It comes from a creek in south central coastal Queensland. The temperature tolerance of this fish is not as wide as the Dawson rainbow, however it will survive at normal room temperature. A heater will not be necessary in the average home aquarium. This is the first commercial production of this fish.
Dawson River Rainbow
The Dawson River runs into the Fitzroy River. The Fitzroy Dawson River system is limited to Queensland. It drains a large portion of Central Queensland and empties into the sea at Rockhampton. This is right on the Tropic of Capricorn. Although this is in the tropics, the inland reaches, where our brood fish were collected, is very cold during winter. These fish are very robust and are able to tolerate very high temperatures and long periods of cooler temperatures. They regularly endure temperatures around 11C.
This fish has been grouped in as a Melanotaenia splendida splendida, but some scientists believe it probably is more related to a M. fluviatilis.
Barcoo River Rainbow
The Barcoo River is one of the rivers in Central Australia which drains inland. Eventually empting into Lake Eyre.
These fish inhabit one of the most unhospitable riverine environments in the world. Water temperatures vary wildly through-out the year. Even in a 24 hour period this region experiences enormous air temperature ranges. Overnight low can be about 12 Celsius in summer with a daytime high in the 40s. In winter overnight lows can be below freezing, while the next day can be in the comfortable 20s (Celsius). General water quality is also under pressure as the flow of freshwater is infrequent to say the least.
This means, this little fellow makes a very hardy aquarium fish, able to suffer the consequences of the casual inexperienced fish keeper. A heater is not required under normal conditions for an indoor aquarium.
These are excellent fish. Known as "neon" rainbow they are also known as Melanotaenia praecox. They are perfect examples of what the PRAECOX were when they first became available commercially in Australia. They are hatchery spawned, pond raised.
Because they have been raised in the pond the body shape is perfect as is the colour.
They are also strong, disease resistant fish, as a result of having to survive in a natural pond. To the best of our knowledge. Ausyfish Pty. Ltd. is the only commercial facility producing Praecox in earth ponds.
These Parkinsoni rainbows are the orange colour form. A number of colours are in the hobby. The main colours are orange and yellow. Although the colours are considered by some to be completely separate forms, it is possible for any of the colour forms to have some of the other colours in each batch.
As the fish age the colour gradually moves over the body of the fish, starting from the tail. Young fish don't have any colour. The fins develop colour first. The large fish shown in these pictures are only one year old. Over the next few months the colour will cover most of the body of the fish.
Opals In My Pond
Australian native fishes have been almost secretively admired by an ever increasing number of ornamental fish keepers world-wide. The most famous of these are the Rainbow fish. Australia is famous for it’s opals and the Australian Rainbow fish is the opal among the world’s aquarium fish. Like the opal the colours of these Rainbow fish are sometimes bold, and sometimes beautifully subtle.
Australian rainbows are also ideal for mosquito control. It is possible to cause the extinction of one of our rainbows by stocking your garden pond or farm dam with the wrong colour morph, even if it is the correct species as advised by authorities.

A wide variety of Australia’s native fish are suitable for use as aquarium fish. Many of our Grunters, Gudgeons, Blue-eyes, and Hardyheads make ideal aquarium specimens.
The smallest of these are the Blue-eyes, ranging from a little over a centimetre to around 4 centimetre. The Grunters best suited for the large fish enthusiast. The Silver Perch being one of the best known of the Grunters in some parts of the world. However the Coal Grunter, a smaller species, known by a lucky few, usually only reaches about 15 cm in the aquarium. This fish shows a beautiful gold and black chequered pattern as a juvenile, gradually changing to a gold /black sandy appearance as it matures.

Commercial culture techniques for Australia’s aquarium fish are as wide ranging as the types of fish. Some fish will simply reproduce in small ponds, while others require hormone induction. Many of the Rainbows are quite co-operative and a small pond of around 10 by 20 meters will produce thousands of 5cm fish. Other varieties of Rainbows need to be spawned in aquariums, or a hatchery. The Grunters are the most difficult, most needing hormones to induce spawning. The beautiful small Blue-eyes will also breed in aquariums, but after some trial and error these too can be coaxed into reproducing in earth ponds.
