I have 2 goldfish in my 10 gallon right now. (Please don't lecture me about it. I already know, they grow big and raise ammonia, and yes, i check my water. the pH and the ammonia is at a good level.) Next time I want something more interesting, like a Betta/Neon Tetra/Oto combination, or a Guppy/Oto combination,would these work well, and could i get the numbers that could go into a 10 gallon?Thanks for alll your help.The people in the fish section are great. =)Oh yes, and I DON'T want to breed the guppies.i meant after i'm done with the goldfish.
