spawning

I have 2 female and 1 male silver tipped tetra in my community aquarium. Today the male chased a female in a "courting dance" and she released a bunch of eggs all over the aquarium (which other fish then ate...). :( I know they are an egg-scattering specie, but is it normal for this to happen...

Had many spawns before this one with other pairs but they havent been able to grow bigger then a nickel. so im hoping that these babies reach an amazing size. just like the parents. I dont know what will come of this thread. But i just want to share my video and im open to any info you all have...
