I don't know if this counts, but my favourite fish I've ever owned would have to be my first fish... a betta. He's not around now but he was the first inhabitant of my first (and currently, only) tank (a 20g.) The tank has come a long way, but he's certainly left his mark.
Of the fish I own currently, I'd have to go with my 1 female cherry barb. A really lively fish, probably the drabbest as far as colour goes, but the liveliest as far as attitude (that sounds odd, can fish really be considered to have attitude... Ahhh, who cares, they have some sort of mind in those tiny heads of there's.)
