5 Gal Hex Stocking

Dwarf Puffers or a betta or some endlers, are your only option.
 
Honestly, I believe a 5g hex is just too limiting. I bought one a couple of years ago, and have found it's just too small for much but fry, or a snail or two, or short-term growout tank. Or a hospital tank. The footprint is so small . . . . the concept is appealing, but if you really want to do a few fish aside from killiefish/endlers, move up to a 10g or 29g. Good luck in your decision!!
