My fish tank is finally cycled and I'm ready to add fish. My ammonia is 0ppm, Nitrite is 0ppm and Nitrate is 10ppm (API master test kit). I already have an established 20 gallon tank with fish in it that I want to transfer to the newly cycled tank. My question is how many fish at a time should I add since I have schooling fish. The new tank is 40 gallons. I have the following fish in the 20 gallon.
6 White skirt tetras
4 Otocinclus catfish
12 Neon tetras
