Answer 1

I dont know where some of these people get their information but koi and goldfish most certainly can and do breed...the babies
grow quickly and have characteristics of both fish, I've always thought they looked liked sharks

Answer 2

If the temperatures are 50 or lower, you should NEVER feed your pond fish. They have entered into a state of hybernation. Their body metabolisms have slowed or stopped. Feeding them will not allow the food to be digested there fore rotting in their inners all winter causing build up of toxins and then death. The eggs and fry were probably there in the fall you just didn't notice them. The small fry don't need anything to grow over the winter since they too are in a state of hybernation.

(Have have hundreds of new ones every spring after the thaw!)
As long as the water temps are above 50 and remain above 50 you can start feeding. If the water temps are dropping below 50, DO NOT FEED THEM.

Honestly, it is a bit early to be worried about cleaning the pond. (Unless you live in Florida). I never clean the ponds too early for fear of loosing the babies by accident. If you must clean the leaves use your net and a bucket. Scoop out the leaves and some water and place them into a bucket (tub or what ever you have) I had pick out the leaves and dump the water back into the pond. I do this about 3 or 4 times before I turn the filters, waterfalls and lights on in the ponds. You can use a very large siphone to clean the bottom, again strain into a fine mesh net and a bucket. Even if you suck up a few little ones you can put them back into the pond.

I would suggest in the fall when the leaves begin to turn, cover your pond with a bird net (leaf net) this will save so much time in the spring with those pesky leaves and keep the nitrate levels down. (Even though leaves do not rot creating nitrogen in the winter, they sure do a number in the spring). This is so helpful every so often remove and clean the net of leaves. You can leave it off for winter though.

Again, don't feed when water temps drop and stay below 50. Don't cut holes in your pond's ice or bang on the pond in any way. Feed again in the spring when water temps are about 50. you will soon have more fish than you know what to do with.

Good luck.

PS YES koi and goldfish can breed. All gold fish come from Carp, Koi, goldfish shabunkins etc.

However, if you keep shabunkins in a koi pond, they will eat the koi babies!

Answer 3

Koi and Goldfish, though similar in both being "carp", are not the same species nor are close enough to interbreed.

It's likely both kinds of fish have just been eating whatever small creatures could fit into their mouths and one group or the other decided it was time to spawn. Or some local fish somehow managed to infiltrate the pond, but I gather that's not very likely.

I doubt they're very old, but especially if they are Koi, they're going to get big fast. I suggest skipping on cleaning for the moment. Figure out if the increased population is sustainable by the pond, you might need to give some fish away or take to a pet store (but don't throw them in local waters).
When the babies are not babies anymore, then clean the pond, but just enough to get out amassed leaves and similar garbage. Leave any plant life that's growing, unless you're planning to replace it with an ornamental variety. Do make sure you have a working and efficient filter. As temperatures warm up, pick up on feeding, but the metabolism of fish are directly affected by temperature, and overfeeding will lead to a more dirty pond. So back off while temperatures are down.

No,kois cant breed with goldfish.Here's some tips.
Although a pond is a significantly larger body of water than an aquarium, the same rules about stocking the right amount and type of fish apply. In almost all scenarios, you will be supporting goldfish or koi, both of which can grow quite large and are messy eaters. That means that you will require robust mechanical, chemical and biological filtration, just as you would in an aquarium. Keeping water moving in the winter will help prevent it from freezing completely to the bottom.
Live plants are a must. Aside from their natural beauty, they will out-compete algae for nutrients and keep it in check!!Remove visible debris from the pond with a net on a regular basis!yep! Do not let dirt and mud fall into the pond and keep leaves and other foreign objects out!
Feed your fish according to the water temperature. In warmer water, fish need to eat more often, while in colder weather, they may not eat much at all.Much food will go uneaten and will pollute the pond, creating more work for you and your filter.
Hope this helped!!

Answer 5

Yes, koi and gold fish can breed. They are both carp. My step father breeds koi, he has had crosses in the past.

Answer 6

Koi and goldfish are similar fish and can interbreed. If you want the babies to survive,get a good pond filter and do a water change. Feed them flake food,daphnia,worms. Make sure the water doesn,t get too cold for the delicate newborns.

Answer 7

Yes they can and do. Koi/comet hybrids are massive fish without the barbels that koi have. They can reach 4 feet easily in proper conditions. Somthing about the hybridization of the genes makes it so they grow bigger and faster than koi or goldfish.
