Overview

The Eastern Rainbow, also known as the 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 Eastern 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 Eastern Rainbows have large mouths, their throats tend to be narrow. With this in mind, foods should not be too large. The Eastern Rainbow is an omnivore and should eat a mixed diet of flake foods, live foods, and plant matter.

Customer Testimonials

I have kept Australian Rainbow Fish for many years-they have proven to be some of the most easygoing and hardy fish I have ever dealt with! The comment on LiveAquaria.com about them having narrow throats couldn't be truer, though. They have a habit of spitting up pieces of food several times before finishing. This makes quite a mess of feeding time. Therefore, if you are going to successfully keep Aussie Rainbows, it's best to have several bottom and midwater feeders to help eliminate the waste. They are definitely worth the trouble. You will most likely find them becoming a necessary addition to a least one of your freshwater setups!

I have 2 of these beautiful fish and I must say these fish are gorgeous. They look even better now than they did when I got them and I believe the male is turning from gold to red to black within a ten minute period One of the best buys ever!!

I have an Australian Rainbow who is full size and been with me for over 4 years now. A very hardy fish that I would recommend for any beginner fish, Mine has been through alot (very hardy).

The Australian Rainbow is a very beautiful fish. These fish look even better in groups of 4-6. If you have a few of these, your freshwater tank will look like an ocean. They swim so gracefully, always following each other. They are peaceful and avid eaters! Although their colors are not so intense as other certain Rainbow fish, they are still a pleasure to watch and a joy to have. I highly recommend these fish either as a species tank or as peaceful community occupants.
