I have a 10 gallon hexagonal tank which I got to house my last fire bellied toad 3 years ago. Since said toad has passed on (  ) I've struggled to work out what to put in the tank. For the last few months I've been using it to keep 3 rescued serpae tetras alive but now I'm looking to either rehome them or risk putting them in one of my communities.

So...
Any ideas what can live in such a tall and weirdly shape tank? I feel guilty putting anything in something with such a small surface area - even guppies or tetras but I can't trade up as it's all a bit DIY 
 
HELP.

  Thinking about it, there is a beautiful blue butterfly with cellophane fin fringes at my LFS.
