Comments:
The Australian Rainbow, also known as the Western Splendid Rainbow, is one of
more than five subspecies of Melanotaenia splendida. Rainbowfish are
known for their characteristic large eyes, black or silver band that runs
through the middle scale rows, deeply forked mouth, and two dorsal fins.
This peaceful Rainbow is a schooling fish that thrives in a planted aquarium,
but not too densely planted that there is insufficient free-swimming places
available. The aquarium should have a gravel substrate; the colors of the fish
may intensify with a dark colored gravel.
An egg layer, the Australian Rainbow reproduces more easily in a separate
breeding tank with a moss substrate. Courtship begins with the male displaying
his brightest colors. At a temperature of 75°F, the fry will hatch after six or
seven days. After the fry hatch, the adults should be removed from the breeding
tank. The fry should be fed an omnivorous diet starting 24 hours after they
hatch, as they are still being fed by their yolk sac.
Although Australian Rainbows have large mouths, their throats tend to be
narrow. With this in mind, foods should not be too large.
