Fish Fanatic
I've been debating recently about purchasing a 6-10 gallon tank. Knowing the size, I'm thinking of either getting a betta or dwarf puffer. Which should I go for? There are so many pros and cons of each I can't decide. 

fanning around in the water and blowing the substrate around. they are just as fullfilling as our lovely bettas, i would have the betta though
