I thought about that earlier lol, I added 1 of my Red eye tetras and waited til morning. Nothing changed in levels, so I added another. That changed ammonia from 0 to .5 so I am waiting another day or so til I add a 3rd. I'm moving some of the fry to my main tank instead. The 3 red eyes I have in there don't go after the fry I have in the main. Gradually moving the reds to their own tank and adding more of them.
