It'll be ok until you get a breeder box tomorrow at fish shop. Get floating plant too and put some in the breeder box. Crush those pellets you have and sprinkle in with fry 3 times a day. Not too much at once. When ever I had some extra at the bottom I would clean the fry box. Gently poured the fry into a big hug, cleaned box, put them gently back in. I did water changes on the main tank daily and within 2 weeks my Fry had great growth. They then went back into main tank.
