Today I experimented with 3 different fluorescent bulbs trying to see which one makes Rasbora kubotai look its best.

I used 3 bulbs:
1. Very warm Phillips brand (Kelvin probably about 3 000)
2. Giesemann Midday T5HO (rated 6 000K, the best bulbs for planted tanks, an amazing mix of warm and white light in one single bulb)
3. A nice and obsolete Power Compact - 10 000K - white as it can be.

I have a huge school or R. kubotai - about 200 fish. I write this post because the fish looks absolutely stunning under a lot of light (2.5 wpg). The best color showed under the white light. But this same light washed out the green of the narrow leaf Java Fern in the same tank. There is a sort of visual interaction between the green color of the Java Fern and the green R. kubotai. The white light emphasised the fish more.

The Giesemann Midday once again would be the best choice. It made the fish look neon green AND kept the Java Fern looking fresh green.

The R. kubotai appear to change colors depending on the angle of the fish. Definitely the bigger the school the better. The green color of this fish resembles neon green aluminum foil. There is no other fish that looks like it. A few of the fish in my big school are R. nana - they do look like a reddish version of the R. kubotai, but mine are still young and I could not tell how they compare to the bigger sized R. kubotai.

Overall - now I too know why R. kubotai is such a desired fish.

Bunbuku,

The fish is small - the adults reach a little more than 0.5".


MudPieMama,

The picture above is not mine. Once again - it only suggests how the fish looks. If you see the kubotai live you will think you will never want another fish.

Maddyfish,

I have the fish in a holding tank and it just so happened that there was a single piece of Narrow Leaf Java Fern about 10" long. That's how I saw the green color of the fish and the green color of the plant interact.

I took some pictures of the fish yesterday. But it's hard to show them in full glory. Here they are, you can see that on some of them the white ballance has been changed and the green color appears cooler.
