Care & water parameters

Contrary to some popular opinion, these Rainbows are very hardy provided you provide adequate space, good filtration (they thrive in planted tanks)and don't let the water get to hot (>84F). They will handle low temps better than most tropicals. These Rainbows prefer temperatures in the 72-78F range but will do very well with temps down to about 62F and up to about 84F. Hardness doesn't matter as much as temp as they are found in extremely soft and hard waters depending on the seasonal changes. PH should be kept between 6.5 and 7.5. These fish are omniverous and will thrive on a diet high in animal and vegetable proteins such as top quality flake feeds, and any form of live, dried or frozen brine shrimp.

About this fish

This is another rainbowfish from northwestern Australia that has many variations depending on the river in which it is found. One of these varieties was probably the first rainbowfish introduced to the hobby in the 1930s. Our strain comes from the Alligator River in the Northern Territory. It grows to about 3+ inches, is very hardy and is suitable for community and planted aquariums.
