On this page I will give an example of a set up you might want to try.

Australia / New Guinea river.
A tank for the Rainbows of Papua New Guinea, where shallow slow moving
sandy rivers dominate the landscape. A species Biotope.

The size of the tank is not overly important, what is important is that
it be long as the rainbows like to school and are an active fish species.
A standard 55 gallon or the less common 40 gallon long will do fine.
You can even go as short as 36 inches if you want to cut back some.
Because the Rainbows inhabit sandy rivers the substrate should be a
fine gravel with a gentle slope at one end. Do not use an undergravel
filter as the depth of the gravel will inhibit its' effectiveness. A
power filter is best and put on one end can simulate the flow of a river.
You can use selectively placed rocks but no bog wood, as the current
would be impaired. Plant the tank heavily as the Rainbows are more at
home with it. Remember to leave plenty of running room for the fish.
Here are some plants that can be used, all are not native but should
work out fine.
- Polygonum attenuatum
- Ludwigia octovalvis
- Pseudoraphis spinescens
- Cynodon dactylon
- Cyperus carinatus
- C. conicus
- C. vaginatus
- C. javanicus
- Ipomoea sp
- Hydrilla verticillata
- Myriophyllum verrucosum
- Aponogeton Crispus
- Najas tenuifolia
- cryptocoryne wendtii
- Salvinia molesta
- Spirodela oligorrhiza
- Nymphoides indica
There should be water movement and a small flow power filter can be
used. The lighting should be bright but not overly intense. Two standard
full spectrum tubes will be sufficient as the tank is fairly shallow.
The water should be low to medium in Hardness with a pH between 6.5
and 7.0, A temperature of 75o (24 degrees C)can be maintained
with a standard aquarium heater.
