I currently have 5 Neon Tetra's and I have plans to get another 5 in the future. I was wondering if I could get 5 more in a different type of tetra such as a Black Neon Tetra or would be best to have them all the same??
well most people recommend a shoal of 5-6, so you should be alright with different species, but they won't shoal together if that's what you mean. How big is the tank?
