I have some ember tetras that I think are only a few months old, they’re small and the guy I got them from said they’re gonna grow. I had some fry food so I put some in and they went crazy for it! They did go for the tropical flakes but not as much as the fry food, but a lot of it made it to the bottom. Will feeding them fry food be good nutrition for them? I’m also going to grind up some baby shrimp for them and my Betta. Also, How much powder do I put in fro 10 tetras? I added a pinch.
