hi and welcome to the forum Smile

unless you are dealing with wild caught rainbowfish (unlikely unless you live in Australia or New guinea), you can keep them in water with a pH between 6.5 & 8.0, and a general hardness between 50ppm & 300ppm. Temperature between 22C & 30C.
I use to keep the pH around 7.5 and general hardness around 150ppm, but I also had rainbows in rift lake tanks with cichlids and the pH was close to 9.0 and hardness over 300ppm.
Wild caught Iriatherina werneri and Rhadinocentrus ornatus require slightly acidic water (pH around 6.0 to 7.0).
Lake dwelling rainbows like Melanotaenia boesemani come from alkaline water pH around 7.5 to 8.0.
Most other rainbows from rivers and creeks occur in water which fluctuates depending on the time of year. It can vary between 5.0 & 8.0, depending on rainfall and tannins.

The type of rainbowfish you keep will depend on what you like. In a 29gallon tank you could keep 10 or so adult rainbows that grow to 4inches long. You can keep them with most catfish, loaches, barbs, bigger tetras and smaller peaceful cichlids.

you can get more info and pictures of different species from Adrian's e-book (Adrian Tappin's: Rainbowfishes - Their care & keeping in captivity), found at the following link. It's a free download.
