Pudge the Fish

Well, it has been a very very sad few days, because my fish Pugeball Gillgamesh passed away a couple of days ago.. And I'm not being sarcastic about this cause he was a great fish! and I was genuinely upset about it.. still am, but I'm setting off for a new fish this Friday on meh Birthday! Cause my friend Emma and I got Pudge last year on my birthday, and shall do the same for my soon to be new fish, Finnigin Douglas.. Anyway just thought I'd share that sob story with you, ANy suggestion on what kind of fish to get?? Non-fliter preferred! :) thanks!
