I started fishkeeping in 1968 and have had fish continuously ever since. I went down to only two tanks in my college dorm room (1 fw, 1 sw) in 1977 but once I bought my own house in 1993, my number of aquariums grew quickly to the present count of 59. I started my own pond maintenance business in 1999 (still going), so add another 16,000 of outdoor tanks and ponds. 43 years and still as addicted as ever!
Using 1.2 hours/day rule:
1.2x365x43=18834
But for the last 13 years it's really been more than fulltime between ponds and aquariums. I would add 40 hours per week for 13 years:
40x52x13=27040
Grand total would be 18834+27040=45874.
I don't know whether to be proud or embarrassed about that.
P.S. I never spent any time chasing girls because I am one.
