Name: Melanotaenia trifasciata
An extremely cool fish. This fish is accompanied by about 20 different color varieties. I read this in a book. Not my own information. Most rainbow fish are usually hardy and peaceful. They will generally show changing color patterns due to environmental factors and other factors like sex. Great fish, but will sometimes come with a price tag of around ten to twelve dollars a fish, maybe a pair. This fish will add color and life to an aquarium at least 120 L in size. These fish will readily eat live insects as food. I am sure this is because they eat insects in the wild when the bugs fall to the water and can not get out if the water.
What a fish, I've only just started with 5 trifasciata and they're awesome. The most fearless little fish (they're only about 3 cm, but have already begun to color up red on dorsal. Highly recommended!
The Goyder River rainbows are great fish to keep like all other Australian rainbows. New Guinea Rainbows are the ones that tend to be talked about overseas, but I think the Australian ones are just as colourful. All Rainbows I have found do not get along with giant danio and barbs, as they become competitive with each other, but are living with an angel fish, congo tetra, blind cave and florida flagfin with no problems in a 430 liter tank. I also recommend that you buy a male and female so the male colours up more. I have been collecting in my tank a male and female of different species, where each species develops its own colour. Be patient, as rainbows have no colour when they're young.
I have five Goyder River rainbows, as well as other types of rainbows (for around twelve months), and I have never found them to be competitive in any way towards my tiger barbs. I think it helps if you have a large enough tank. I'm lucky enough to have a 4000 L so there's enough room for all. The rainbows are my favourite fish when it comes to feeding them live insects as they attack them at full speed - no other fish has a chance.
These fish look spectacular when they are full grown. They are very enthusiastic eaters, I had a house fly drop into my tank...it never had a chance. These fish are worth the money you pay for them.
This fish is very colorful, active and fun to watch, but is very aggressive towards my 3 other male rainbowfish (Boeseman's, Dwarf and Red). The three other Rainbowfish get along fine with each other. They're all still small and none of them bother my 4 Tetras, 2 Silver Dollars, 2 Balas or Pleco in my 280 L tank. They are very aware of what's going on outside the tank and get excited when they see me coming with their food. They go crazy at feeding time. I think the Dollars feel a little overwhelmed by the Rainbows even though they're much larger.
There are many different types of Melanotaenia trifasciata and these types are based on the locale they are collected from. The fish in this review is not a Goyder River Rainbowfish. It is a Banded Rainbowfish, Goyder River or Melanotaenia trifasciata, Goyder River. The Goyder River is just one of many locales and color variations that banded rainbowfish are found. Goodie River, Wonga Creek, Running Creek, Pappin Creek, Coen River -- these are just a few more of those color and locale variations.
Although Australian Rainbows are beautiful fish, they are really very active and do intimidate more timid species by their constant movement and chasing. When I removed my Rainbows, I noticed an immediate behavior change in my Leeri Gouramis and my Bleeding Heart Tetras, which seemed more at ease and swam more in the center of the aquarium in the space formerly occupied by the Rainbows. Too much activity on the part of one species can produce these subtle and unexpected results.
