Rainbow fish attacking everyone in my tank!!

What are the tank dimensions (length x width x height)?
Most rainbowfish need a tank that is at least 3 foot long.

You could get a double tier stand and have one tank above the other. Then you could have rainbows in one and tetras in the other.

Here’s the rainbow Colin. Also huge discovery this morning!!!! The molly has 2 baby danios in with it!!!! My purple glo danio was huge last week. Figured he (I bought 2 males) was eating too much. He slimmed down this week suddenly but I had added the guppy and molly so thought more to share the food. Um nope not the problem. He is a she!!!! What do I do with these 2 babies? Add them back to main to be with their mom?
Also I feel awful. The eggs must have been in the rocks I scooped out for the vase to house the molly overnight.

The rainbowfish looks like a Melanotaenia lacustris cross (hybrid) and will probably grow to 3-4 inches long. It will need a tank that is 3 foot long or longer.

What colour are the baby danios?
They are probably baby mollies. Danio babies are tiny and transparent when less than a month old.

Female danios are bigger and fatter than males.

You can buy breeding nets from pet shops or online. These are fine mesh nets that fit over a plastic frame. The breeding net sits in the aquarium and has a couple of metal tabs that hang over the edge of the tank. the baby fish can be put in the net.

I took pics the best I could

They are baby mollies. Put them in a breeding net and feed them newly hatched brineshrimp and crumbled up flaked food. You can buy dry brineshrimp eggs from pet shops or online.

When catching the baby fish, use a net to herd them into a container of water and lift them up in the container of water. Do not lift baby fish out of water because you can injure them.

There's more info on culturing foods for baby fish, including hatching brineshrimp eggs, at the following link.

darn I was hoping for danios. Okay well do I give them to the pet store? I can’t house this many fish!
Also added the molly back to try things out again and that rainbow is going nuts again. So it’s specifically the molly

Pet shops don't normally take newly born livebearers, and those that do take them usually feed them to something.

I wish you lived close by! I have two tetra glofish, 1 molly, 1 platy , two guppies and a electric blue ram Cichlid ! I love my molly! She’s so cool
