Here's my two ponds, 2000L fancy Goldfish (that I've really become attached to) pond. And another 2000L pond that I was previously using to breed blue crayfish.
Here's that crays I gave up to keep Koi instead,
Did a full pond clean today and gave me a chance to have a closeup look at my Koi friends,
Plan is to upgrade from the 2 x 2000L ponds as my Koi grow to a single larger pond.
Cheers
Mick
