whats the lowest temperature pond fish can live in?

Answer 1

Actually, in many areas, the ocean is COLDER than freezing; it doesn't freeze because of the salt. A select few fish can survive in these areas because they literally have anti-freeze in their veins that keeps their cells from crystalizing.

But I'm guessing you have plain ol' goldfish or koi in your pond. These are coldwater fish and can survive for a while in below freezing water. They won't live if the tank is frozen SOLID, but if you make sure to break the crust of the ice to allow for gas exchange, your fish will be fine for a while (a few days to a couple weeks).

So, in 32F, the fish will pretty much go dormant. They will not eat and will move very little. They can survive this for a week or two. 33-43F, the fish are moving very slowly and eating very little - so feed high carb low protein foods like cheerios, because they are easy to digest and will not sit in the fish's stomachs. 44-55F, goldfish are mildly active but should not be fed too much. 55F and up, goldfish should be fed as usual.

If you have a tropical pond, they won't survive much lower than 62F.

Answer 2

make confident your pond is a minimum of a foot deeper than the frost line and insure with a pond heater that you save an open hollow interior the ice all iciness. this would help the fish live on. The fish you want is fancy Koi or also a fancy finned goldfish (not bubble eyed or fat chop up tail). Get some goldfish which have spots (calico), lengthy fancy tails or different markings like pink, white, brown. purchase them basically interior the spring and watch them develop up via the three hundred and sixty 5 days. Gold fish actually have personality and could beg for nutrition too. They make good pond pets.

Answer 3

Typical pond fish can survive water as low as 40 degrees F.

Answer 4

well NO fish can survive if the water is below 0 deg Celcius (Because the water's forzen!). But if the surface is frozen--This will insulate the water beneath to several degrees (1-7) enough for some fish to survive. Obviously tropical and temperate fish will die. Fish from the New England (can't name any off the top of my head) area may be able to survive.

Answer 5

It depends on the fish. If you have a pond full of Pacus, they are probably going to die if the temp goes under 60. If you have a pond full of arctic grayling they can survive temperatures barely above freezing.

Answer 6

They are tougher than you think and start dying when the temperature is approx 4 degrees below freezing. I would suggest you heat your pond, your local pet superstore will be able to help you with a pond heater.

Answer 7

as long as all the water does not freeze they will be ok , but what kills them is the lack of oxygen in the water , so if you put some balls on the water the movement of the should slow down the surface freezing if it does freeze over put some hot water on the ice to melt it but do it in a sensible way as not to shock the fish with a sudden change in temp, if you have a pump in the pond leave it running as the flow of water slows down freezing as well and puts oxygen into the water

Answer 8

Usually the rule is: if your water isn't completely frozen and there is a thawed spot/opening on the surface so the fish can get to the air they will be ok. It slows their metabolism down so they won't eat as much but as long as they don't freeze solid they are ok. It is ok if the top inch or so is frozen just make sure there is a hole in the ice.

Answer 9

as long as your pond is deep enough I think that they can withstand pretty low temperatures, as the water rarely freezes to the bottom. hope this might help

Answer 10

i assume you're talking about goldfish and koi, remember they come from Japan and China and it gets VERY cold there,
both species will be fine as long as the water doesn't freeze solid
(so your pond must be deep enough to not freeze solid!)
