Please answer We have a 4500 gallon pond outside I was wondering how many fish can stay in there?

Question

we have about 50 comets and 20 Koi. How many more can we put in there. We have a comet and its side is bulging we think it is pregnant we put it in a tub in the basement. We were also wondering if the mom or any other comets or Koi will eat her babies. Does there have to be a male involved to have babies. because we got them for free and we arent sure if they kept the dad or not. should we keep the mom in the tub or seperater them Thanks a lot

we have a few pump and a water fall in it to keep the pond clean and circulated

should we have left her outside with plants or put her inside with plants

Answer 1

How many fish you can keep in your pond depends on several extra factors. Is it filtered? Do you have some type of pump to move the water or aerate it? how deep is the pond? Is it all the same depth or various depths? What is the surface area of the pond? The more of those I know the better estimate I can give you on a total number of fish.

All of that said, I doubt you have room for any more fish in your pond. All of those fish get quite large and need plenty of space.

For goldfish to breed they need both the male and female to be in the same tank or pond when the female lays the eggs. Here's some more on goldfish breeding.

Answer 2

The one inch of fish per gallon of water is a good rule of thumb. Koi get much bigger than goldfish, though, so if you don't have a lot of natural die off, you may end up having to find new homes for some of your fish as they grow and the season progresses. If you hyperfilter, i.e., filter the water so that you have total pond volume turnover more than once per hour, you may be able to get away with having bigger/more fish in there, but this is not something to be attempted by beginners.

Goldfish and koi are both egg-laying fish. A goldfish with bulging sides is either egg-impacted, got dropsy, or some other kind of disease/disorder - go here to check it out: http://www.koivet.com/. The goldfish will not spawn (lay eggs) by herself. If you want her to lay eggs, put her back in the pond with some boys. They will push up against her to get her to release her eggs, then they will release their sperm to fertilize them. She will not release her eggs by herself, and these types of fish are incapable of any internal fertilization.

As a side note, it is entirely possible for koi and goldfish to interbreed, though any offspring is likely to be rather unattractive (rust-colored, somewhere in between koi and comets as to size and appearance) and sterile.

Both koi and goldfish LOVE eggs, and they will pick the pond clean of any eggs that are laid within 48 hours - including the mom. If you want any of the eggs to survive, you'd better be prepared to remove them (usually by removing the plants or whatever the eggs "stuck" to once they were released) and relocate them to another pond or pool. The eggs look like grains of coarse salt - they are very sticky and will stick to the sides of the pond, roots of plants, etc. Depending on water temperatures, the eggs may take anywhere from two days to a week to hatch.

Once the babies have hatched, you still need to keep them seperate. Comets (and other goldfish) will eat any fish that can fit in their mouths. Koi, on the other hand, will leave the babies alone once they are big enough to recognize as a fish - generally when they are around two inches in length. Again, depending on food availability, water temperature and quality, and size of container, this could be anywhere from two to six months.

Hope this helps!

Answer 3

The Koi need a lot more space than the comets.
Koi need almost 25 times as much space.
Yes the other fish will eat the young unless you provide a place for them to hide. You need to have weed beds and shallows.
A male has to be involved at some point, usually after the eggs are expelled. Probably you are best to allow the pond to reach its own dynamic equilibrium.
Good luck.

Answer 4

1 gallon of water per inch of fish. Separate the mom and the fry from the other fish until they are about a 1/2 inch to an inch long, then put them all in the pond. Nature will weed out the weaklings. It sounds like you have the room for them and depending on how many fry survive, maybe even room for more.

Answer 5

Your acceptable fish load will depend on the size of your fish, the size of your pond and the power of your biofilter. Bigger fish will produce greater quantities of ammonia at a rate that increases exponentially with their size. Your best bet is to buy an excellent test kit and test your water frequently. If you have constant problems with high ammonia and nitrite, you have too many fish or not enough filter.

Answer 6

Its suppose to be 1 inch of fish for every 1 gallon of water. I doubt you want to measure all fish so just guess

Answer 7

i'd say 1 per gallon, so about 4500 fish!!!

wow!!
