I seem to have good luck with danios. I've been keeping fish since I was 6 (27 now) and I only have to go back about 4 generations of danios to get back to the very beginning of my fish keeping days. I had one that actually lived 8 years. I was in middle school when I got it, and by the time it died I was about to graduate college.
What's the longest you've had a fish live?
