Assuming they are Columbian tetras (common names used by fish stores can be deceptive and inaccurate) they are Hyphessobrycon columbianus. A photo is attached.

Like all tetras and characins they are egg layers. A pair will spawn and lay the eggs (hundreds) and the eggs will hatch and when the yolk sacs are consumed the fry are free-swimming. They will require very small food, newly hatched brine shrimp is usually the easiest to provide. Here's a link to an informative article on spawning and rearing the fry:

Thanks for the reply. I guess there not columbian. They have a red strip spot over there eyes. silverish gold body. My lfs told me they were columbian tetras. I just looked on a sight i think there the rio tetras.

Fish stores sometimes make names up. One of my lfs, very reputable one, recently had some "Silver Tetras" that I had never seen. Knowing the owner, i asked her if she had a scientific name from the supplier (even they sometimes make them up if not certain themselves, but it can give a hint) and she said no, but they had actually come in as "Gold" tetras but since they were more silver than gold she named them "Silver" tetra. Turns out they were actually the silver form of the Brass Tetra, a fish that has five different English names online [forgotten the scientific name at the moment, no matter]. Thus, it pays to use the scientific name if known to avoid such confusion.

I did a quick search of "rio tetra" and it doesn't match your description. Can you attach a photo of what you think is your fish from that site?

If that's what you've got, they're a very beautiful fish. Moenkhausia pittieri is the scientific name, and a photo is attached. I had a shoal of 7 of these several years ago in my 115g cokmmunity SA tank, and they spawned many times; only once did two fry survive (hidden in the plants). This was just luck, I obviously wasn't trying to spawn them in a community tank, the other fish will almost always eat the eggs which is OK. As yours have spawned, you have a pair. The males have considerably longer dorsal fins and they flare them out when they are displaying to each other or enticing the females. Its good to have both males and females with shoaling characins, they behave more naturally and are fascinating. These fish get a bit larger than others like neons, so they need a bit of room, as they are very active swimmers.

That is what it is in the last pic. I ended up haveing 81 babys out of her and she layed more eggs. I realy like them. I do just have a pair. Thanks for all of the info. It realy helped. My lfs told me he wold give $3 a peice so not to bad.

Well done. These are prolific spawners, so in a tank with lots of plants for the eggs and fry and just the parents, you will probably have quite a few fry hatch and survive. What are they eating? A couple of fry can usually find sufficient micro-food in planted tanks, but a large number will probably exhaust the food supply. That article I linked to previously had some info on food, applicable to any fish. Good luck.

All 81 fry are still alive. They eat powdered flake foods. I put baby brin shrimp. They ate some of that. and yes it is very planted. heavly decored.

Sounds like a great success story, well done. Byron.
