feeder fish and koi?

[andyjs]

for a 15'' fish?
i would think a 100g with good filtration would be fine...

Have you seen a full-grown koi? It could barely move in 100 gallons of water

a 15" koi is just baby koi...have you seen the real full grown koi? I saw lots of 25 to 30 inches koi at the zoo.
