Fish Crazy
A 15L tank is very small in my opinion and very little could actually be kept in it. Shrimp are probably your best bet. You could try Endler's livebearers, they would probably be ok.
I would strongly recommend you get a bigger tank though if you want to become serious about keeping fish, and as others have said, the larger the tank, the easier it is to maintain (and the nicer, bigger species you can keep).
Black moors (and all other goldfish) should not be kept in a tank under 100L and again, the bigger the better. It's not commonly realised but goldfish can reach 20cm in size!
Good Luck,
