Since I'm going to have to put Blitz down soon, I've inevitably been wondering what to do with an empty tank. The thought of dwarf puffers came up, and since then I've been hooked on the idea. I already know the care for them and what they need, what I'm asking is how people who have had both bettas and dwarf puffers think they are different. Who is more interactive, who is "smarter"? Post your opinions here, I'd love to read them!
