I wrote that we stocked the 1/3 acre pond 20ft plus deep the other day it is so not fancy. natural spring fed establish for many years with just minnows and now home to bass and blue gill. It has no filter system no water pump just a fishing hole. I did go back today and got 2 trilopod (?) white amur (12 inches) which I think are amazing HUGE fish and 2 koi (peaches & cream) 8 inch) there is plenty of pond weeds and vegitation no algea (well nothing to write about) all levels are fine zero across the board.

My question: Is this an set up ok or shall I say lack of set up ok for the fish. You always here of all the fancy stuff in the smaller garden ponds well this is not a "Garden" pond it is just a POND as for the bass and blue gill I am sure they are fine even the white amur more concerned about the Koi cuz they are stunning. There are no preditors in the pond at this time, fish wise, that can even touch them due to size. Let me know what you think and how in the heck would I even try to calculate the gallons in this pond.

Even thinking when the Koi in the small garden pond out grow it that they can pack their bags to the big pond and live in there.

was not sure if this is a fish question pond question wasnt sure where to post it

White amurs are grass carp. They are like big plain carp that love to eat plants. The sterile ones are sold to prevent them from breeding and possibly getting into the wild to denude ponds all over (exageration of course). I think you mean the ones you got were triploid (three genes). Those ones can't breed.

Your pond is large and therefore should be fine for most fish that can survive a natural pond situation. I do suggest buying an aerator if you can afford one to turnover the pond and aerate it, at least in one location.

Predators will show up including herons, raccoons, and so on.

Using my pond calculator on my site, I find that 1/3 of an acre is 14520 square feet. If the entire pond were really 20 feet (which it's not), then the pond would be 290,400 cubic feet. That is equal to 2,172,343 gallons or so! Assuming your average pond depth is half of that, then your pond is probably about a million gallons! Your pond is more than 500 times larger than mine!

so you think I can put in more fish LOL. GOOD GOD that is alot of water. Ok I put the grass carp in and the koi they are lost now do you think i will ever see them again? and I saw a huge turtle pointed nose (from a distance) is it a snapper? I really want to see the Koi again.
Thanks Robyn. Again.

You can probably add more fish. How many have you put in? Remember, they will breed (except for the grass carp who can't but will still try).

If the pond has a lot of plants and/or algae, you may only rarely see the koi. They are more obvious so easier to spot (but also for predators).

If there's a huge turtle in there, it's probably a snapper. After them, the largest freshwater US turtles are cooters who can be a over a foot long but not often. Most turtles are under 8 or 9 inches except the snappers.

You put in only 2 koi? If you want to see more koi, you can put more in. The babies (1-2 inches) sometimes sell for just a few dollars each. Larger bass will eat small koi of course.

I put in big mouth bass , blue gill all fingerlings appx 100 I know they will multiply and only 2/ 8in koi and 2/ 12 inch carp. Outside of the turtle the koi and grass carp are the biggest things that I have and know about unless Nessy is living at the botom that I have yet to see. I was really hoping that the koi would come up for food. Wanted to make sure they did OK before I added more Koi and this pond is on one of our properties that are for sale so I really do not want to put a bagilion dollars into it. We are building a pond just like it on our property (but not sooo deep). The only things that seem to eat the food is the minnows and the cagillian tadpoles which are rather large.

I just hope they come up so I can enjoy them. There is soo much growing under the water that if they never eat my food they would survive forever. As for the turtle it is a good 15 to 20 in from side to side and seemed to be pretty round and a very pointy longish nose. I will try to get a pic of him.

I have a question ..........if I do get koi for the larger pond would it be a good idea to put them in my garden pond to get them used to me and feeding and then put them in the larger pond maybe that would make them less skittish to come up or is that a waste of time. I even thought of putting my current guys into our new pond that will be on the property but again affraid I will never see them again. Let me know what you think.

It sounds like the big turtle is a snapper if you live in the US. If you're in Florida, it could also be a softshell turtle; they have pointy noses.

The pond on land you're selling is so large, to not see the fish again is almost expected. Certainly, if you get koi used to being fed, they are more apt to come to be fed in a larger setting. To train them, you would have to set up some kind of a signal. For example, you could slap the water five times in a row before you put food in. Otherwise, they won't know you're coming in a large pond. The more koi you have in the big pond, the more apt you are to actually see one.

I am so jealous! I would go insane with a pond that size. If you do start seeing predators I saw a neat product that was basically a sprinkler with a motion sensor. Personally I would prefer the drone guns from the movie Aliens. But that's just me.
