The bright yellow one is a Melanotaenia Trifasciata, commonly referred to as a banded Rainbow. This variation is called Running Creek. They are about 4.5" long, and are showing mature coloration. There are other varieties of Trifasciata, like the Goyder River ones in my tank. They have more red, gold, and black, and are not fully grown yet. They are also spectacular when mature.
where did you get the variety of rainbows? Local or did you order them? I can only find the australian, neon, and bosemani rainbows locally where I am.

It took some searching, but I found them all locally. One of the LFS near me gets a nice selection every so often. I also asked several others if they could find what I was looking for, and they were very helpful.
There are also some places on line that sell variety packs. I didn't go that route, but would have if I didn't have any luck.
I like having a nice mix of Rainbows in the tank. The different colors darting around are very eye catching.
