Easy egg-layer to breed?

Since you only have a 10 gallon I would breed some danios or tetras k have seen people breed glofish they are just like danios but different color and if they bree a glofish with a dan they have turned out purple I think it's pretty cool an they are small an egg layers and easy just loom it up on YouTube and they have one that I like with a net so the eggs fall to the bottom
