    Streams and estuarine waters in Indonesia (Celebes) , near the city of Maros

General Body Form:
    Slender with moderate lateral compression. The most obvious features are the Dorsal fins. The first one is small and lies in line with the Ventral fins. The second Dorsal is much larger and lies in line with the similar shaped Anal fin. In juveniles and females the second dorsal and the anal fins are rounded, while in adult males they are elongated and pointed to separations at the tips.


    A very beautiful fish. In the male the body is translucent Gold, With a Blue-Green sheen when looked at from the from the front. The top as well as the belly area are pale Yellow. The sides are a OliveYellow, with bright Blue-Green stripes running down the length of the body along the backbone. The first Dorsal is a rather unimpressive Coppertone. The Second Dorsal and the anal fin are quite stunning. They are an Orange-Red at the base fading into a yellow as the fin expands. The first two rays are jet Black. The ventral fins have the Yellow tinge and the Caudal fin is pale yellow with dark upper and lower edges. The eye is a Greenish Yellow color.
    The females are generally paler in color overall and the Black edging of the second dorsal and anal fins is missing.

    The tank should be heavily planted in areas, but also have a large open area for swimming. The addition of some floating plants will also help mimic it's natural habitat. Not the easiest fish to care for, they require pristine water conditions. Frequent small water changes are a must and the tank must have excellent filtration. They will accept flake and frozen food, but they will fare better with the addition of live food.

    Slow moving clear streams in the hilly parts of Celebes, Indonesia.

    The spawning period can last for several months. The courtship is fast paced and intense with the male always driving at the female. Once completed the female will lay the large clear yellow eggs among the plants. You will se them hanging by threads from the underside of the plants. They are spawn eaters and if possible you should remove the eggs to a rearing tank. At a temperature of around 80°F the eggs will hatch between five to ten days. The fry will remain just below the waters surface and must be fed the smallest of flake food or paramecia. They grow fast and are sexually mature at around seven months of age.

A lovely rainbowfish. Got 4 of the to go with my other three types of small rainbows. Seem to be doing just great! Very similar in behavior to pseudomugil Furcatus!

I recently had the pleasure of running across 6 of these guys at a local LFS, all are juvies a little under 1" still. I have soft water that is a tad on the acidic side and these guys have thrived in it. Very very active little fish and very fun to watch. One of the nicer species I have ever owned, and actually my first rainbow. Personally I don't think they are very demanding, and they eat anything that is thrown into the tank, I was very surprised at how much they cost, there was no price listed on their tank, I didn't care honestly, but after getting the receipt I was shocked to see they were only 99 cents each, and the owner knew full well what they were. I plan on getting another 6. They are currently in a 55gal planted with a couple female endlers, Pygmy cories, Psuedosphromenus dayi, Farlowella, Otos, and a couple SAEs. I can't wait till they fill out and start spawning, surprisingly they have already gotten to be one of the top fish on my list, even nearing my own Discus that I spawn regularly for a few years. They do seem to appreciate low water movement and have become much more active since I put a smaller 80gph power head in rather than the larger one. As far as filtration, I am only running the powerhead attached to a sponge for physical filtration and for water movement, while the plants do the rest of the filtration. The water stays great as far as quality goes, and I usually only do a 50-60% change weekly. Really not that demanding of a fish in my opinion.

I recently had the good fortune of picking up a school of six of these appealing and interesting fish. In pH of 7, GH 10 and KH 5 my fish are breeding and showing full coloration. They are laying their eggs in large clumps of Java moss.

These are AWESOME fish!!! It took me forever to find one, however. And when I found it, there was only one. I had given up on trying to find this fish when, one day, I was a petco trying to find a dragon goby (which I never did get), when I saw a small, very pretty fish hiding in the corner of the platy tank. I recognized it and asked if it was really a Celebes. The worker said that it was a cross breed that nobody wanted and sold it to me for a buck fifty! (hahaha, they should have known what they were selling). Ever since then, this tiny fish has proved to be my favorite so far, although I can't find it any others for mine to school with. Very interesting fish! If you see one, buy it!!!!

I have three of these lovely fish. They are in a 10 gal. with a male betta (very mellow with other fish) and a yoyo loach. They are doing very well and I think the comment about demanding water quality is slightly undeserved. Although I do regular water changes, I haven't been doing anything special and they are showing bright colors and are always active. Mine readily accept flake food and I think they sneak some shrimp pellets and algea wafers from my loach.

Being a fan of rainbows, I was surprised to see a species I had never heard of at petco (of all places). they were nearly five dollars apiece, so I only bought two, but I am very happy. They were both juveniles when I purchased them, and have grown into a very healthy male and female. I agree with the previous comment about water quality; they don't seem to be too bothered by my low-pH soft tetra tank. They readily accept any food I feed.
