My flying fox ;D second fish I ever owned, he is pushing three years in january. I also had a red dwarf giurami (my very fish) for two years. only had fish tanks for three years in january
I had a Striped Raphael Catfish that I would have had for three years in February. Unfortunately, he died after a big storm caused a three day power-outage last month
i've only been in the hobby for 4 years, so none of my fish are very old yet. my oscar is getting close to 3 years old if he isn't there already (got him in March of 2009 at just shy of 3 inches). my paratilapia polleni is about the same age (got him at a little bigger than the oscar not long after i got the oscar). my albino rainbow shark is probably the oldest of the bunch at about 3.5 years - he came home in mid 2008 as just an itty bitty lil guy.
