I'm thinking of upgrading the fish in my 20 gallon long to a 40 gallon, and would like to do an interesting species tank in the 20.
What are my options as far as puffers go? Am I pretty much limited to a couple dwarf puffers? Are there any other small puffers that can be kept together peacefully that won't outgrow a 20? Or a single puffer that won't?
