I have kept a lot of "difficult" fish, but i have seriously had the worst luck with fancy goldfish. And its not from not doing enough water changes/not big ebough tank etc. I have only had small goldfish, in large tanks, yet they always seem to die of something or other... Is there something Im missing? I like the puppy cuteness of goldfish (particularly lionheads and orandas) but are fancies worth the heartache?
