After going through all different types of fish for weeks, I have decided I really want to have zebra danios and neon tetras in my 12 gallon. I've scratched the idea of putting the frogs in there becuase I keep reading 1 adult needs like 5 gallons itself. I also decided against the glofish because my local petco wants $4.97 apiece?! Ok, so these 2 won't go after each other will they? 5 of each sound good for my 12 gallon tank? Sorry I'm asking so many questions guys I just want to do this right. I was told danios can be used to cycle the tank before adding anything else plus I really love those little guys! Thanks again.
