I'd love to have a gigantic tank of piranhas. <3 I think they're just awesome. Plus, the thought of having them in an aquarium makes my sister just a tad nervous, which makes them even better. I'd also love, love, love an arowana. They're just incredible! They look like water dragons and they're just gorgeous. Love, love, love these fish! <3 First time I saw a picture of one I was like "... Must. Have. Waaaaaaaaant". And I just want one even more after seeing a fairly large silver arowana at my LFS. Maybe someday I'll be able to get a tank large enough to keep one in. An indoor pond for one would be amazing.
