green water = fish viagra ... really? ... try la

that's how japs prepare their fish for breeding during winter. they use green water... but definately can't see the fish having a "stick" poking out from its' belly la...

life span = how well we take care of it... average lifespan still no statistic (that i know of) ... if talking about general... 6 months? (cos some people do put 10 medium fish in a 2' tank and fish keeps dying and owner keeps buying...)

anyone knows the lifespan of goldfish?
