Alright, so you are right, 2 guppies isn't enough. So i added 4 more to make 6 guppies, still not enough:
ammonia: 0
So i am going to add my last few guppies remaining (4 more) and 2 corys. I'm thinking of angelfish, african dwarf frog, guppies, more corys, a few tetras. I don't really have an exact idea of the fishes, but i definitely want an angelfish.
