Alright. I got a 10 gallon and snuck it into my room, and now I finished the 3d background for it, and I want a river biotope. Now I want to breed white cloud mountain minnows for my axolotl, that's why I got the tank. But if fits in perfectly. What are the risks of getting some sand from the river, and pouring boiling water over it repeatedly? Or is there a better way to disinfect? Bleach? Vinegar? Jungle net soak? The river is my favorite place, and my local river runs so clean and clear, I want a tank like that. So sand and rocks from my river, cleaned and sanitized, how? And how many minnows should I start with in order to get some breeding started? What's the best way to condition them? Thanks!
