New pond help!
Wow, all of you guys have such a great wealth of information! I hope that you will be able to help me out with my koi pond questions.
First off, I have a 55 gallon tank with 2 koi, 3 big goldfish, 2 comet goldfish, and 2 plecos. We had to add 2 of the big goldfish in over winter, otherwise they wouldn't survive in the horse troughs. The koi are 6 and 7 inches (roughly), the goldfish are 6, 5, and 4 inches, and the comets are 4 inches a piece. My boyfriend and I have come to the conclusion that our tank is now horribly overstocked since everybody has grown over winter.
We want to make a pond for them, because our tank can't handle it anymore. We would be putting the koi and potentially all of the other goldfish out in the pond. How big should we make the pond? We would like to add others to the pond, too, at some point.
That being said, there is an existing pond already on the property. It's man made, and we're guessing 10,000 gallon aquafer fed pond. It'd never been pumped (by a filter), it was surrounded by birch trees, but when we tested the water it was fine, other than just being murky. (That was last summer.) We just took the trees out. What would we do to make it fish-compatable? There are some little baby fish already out there. We've seen herons and eagles out there, but the pond may be getting a snapping turtle, too...
Now, we didn't read up on anything about koi when we got ours. We bought 3, but one had its' front fin muscles pulled away from the fin itself during travel. (It did not make it, sadly.) Our other damaged good was missing scales, and still has not regrown them. (The tank will be a year old in May, and the koi have been in since...July or so.) Should we keep it in the tank instead of the pond?
Also; Our guys have fin rot, which we're treating for now. How long should we wait to put them in a pond/transplant them at all?
I thank you all for your help in advance-I know we need it, haha
