Is there a way to tell the diference between these 2.
A while ago I put some goldfish in my dads pond... about 3, they were only about 5cm long.
His neighbour has watergardens that sometimes flood and there are Koi in there.
Today I saw 2 very large goldfich about 200mm long and fat as (you should see all the food in this pond). As well as that I saw a Koi carp. It looks different to the suspected goldfish.
It there any way to tell?
Oh yeah, I have been traping the eels out of his pond and putting them in the stream that also runs thru his property where hopefully they will clean up. They tend to come into the pond and never leave and eat everything even ducklings, I saw it myself!!
I guess I should add the pond is about 30m x 15m and about 5 foot deap in the middle.
