I've got a 5 gallon/ 20 litre tank which isn't doing anything, as my big tank is stable and so I don't need the quarantaine tank anytime soon. I've been thinking of setting up the 5 gallon at work on my desk. At first I thought of a single male beta, maybe together with a ghost shrimp, but someone suggested dwarf puffers, and they do sound really cute. What do you think I could keep in a 5 gallon tank? Anyone with any experience in drawf puffers?
Hrmm... that sounds not suitable for an office environment, unlike what is written on the Dwarf Puffer website. Maybe I better stick to a beta, they are easier and hardier.
