Rainbow Fish

Anyone have experience/tips on rainbow fish? I had never heard of them before until recently. Are the "neon blue" rainbows really blue?? I will have to wait a bit before adding more fish to my tank, but I've been trying to come up with ideal tank mates. Rainbow fish keep cropping up in my internet research.

Does anyone on the board own some? How are they as community fish? Are they colorful and personable? Easy to keep? Thanks!

I have a couple of neon rainbows. The body is reflective blue, if under certain lighting conditions. The males have red fins.

Hi girl920,
I owned 8 dwarf neon rainbows(all succumb to columnaris). They lasted 5 months with me and they have spawned prolifically in my tank. Too bad...In the community, my other fish have free meal on eggs. Some eggs did hatched but the fry were eventually devoured.

IME, they are quite prolific. They are good community fish and grow to 6 cm max. They are also easy to keep as long as you maintain the tank well otherwise they'll succumb easily to columnaris.

As these rainbows prefer soft water, pls choose their tankmates carefully. I suggest you keep them with fish from Amazon origin.

As Eddie said, males have red fins and females have yellow/orange fins.

I'd keep those rainbows in a tank of black gravel and pink lighting. Their colors go out excellently.

Feed them with small chunks of food. They may have large mouths but their throats are quite narrow hence my advice to feed them only small bits of foods.

Incidentally, I also have threadfin rainbows(Iriatherina werneri) but their fins make them victims to fin nippers. Threadfins are best kept by themselves but I have kept mine in a community successfully although it's not advisable. As long as you know how to choose the tankmates for the threadfins, you'll be fine.

I'm ready for the pressure.
The drama and the pleasure!
If there is one thing I want to see here, it's HUMOR.
I believe I can fly!
I believe I can touch the sky!
I think about it every night and day!
I stand in awe of my body.
