this sounds a bit like me as i had about 900 goldfish ealer this year
Some hobbyists start off with just the odd couple of fish, but soon find that the 'bug' has got to them, and shortly afterwards they find their homes and every available space is filled with tanks and pools full of the faithful old goldfish, and by this time they have perhaps gone into breeding a few species in order to cover some of the expense for the hobby.
ps i got some nice baby orandas today from lfs
