Help Please* Standard Aussie wall aquarium

And, I'd add, don't underestimate the aesthetic effect that a group of male guppies can have. I was at the pet store the other day, and they have a new display tank--it's well-planted, and contains only male guppies of all different colors. Watching them dart around in the plants, with their iridescent bodies and multi-colored fins, was really pretty stunning.
And, with your tank being so small, guppies are a good choice.
Just don't get any females, or soon you'll be overrun with babies :)


Indeed.

The traditional idea of a guppy being a boring garbage fish has been totally fazed out. there is some really amazing strains and they are now one of my favorite community fish
