Tropical fish, for example, do best between 75° and 80°F, goldfish and other “cold-water” species prefer temperatures below 70°F, and temperate fish can be found in habitats that overlap tropical and cold-water realms.
What temperature is too cold for fish?
It depends on the species, but in general, tropical fish are most healthy in the range of 75-80°F (24-27°C). Cool water fish do better in temperatures below that, usually between 60° and 75°F (15-24°C), but some of them enjoy water well below 70°F, which is not suitable for any tropical fish.
What fish can live in 70 degree water?

Which fish live in extreme cold water?
For example, koi and goldfish are commonly considered to be cold-water fish because of their ability to survive at very low temperatures, but their temperature preferences are 32°C (89.6°F) and 28°C (82.4°F), respectively.
Is 60 degrees too cold for goldfish?
Goldfish thrive at temperatures between 65 and 72 degrees Fahrenheit, which is roughly room temperature or slightly below. When temperatures are too high, goldfish may become sluggish and overheat. At temperatures below 60 degrees, they may stop eating or become lethargic.
Do fish bite in 40 degree weather?

Do fish go deeper when it cold?
As it gets colder, though, fish tend to migrate in schools to deeper water. As the depth increases, temperature stabilizes and it’s easier for them to do their version of light hibernation. … As an added bonus, fish of most species typically hold in tighter groups when the water’s cold.
Can fish die if the water is too cold?
If the water temperature in your tank gets higher than 90°F(32°C), your fish may be in danger of dying.

What fish can live in 72 degree water?
Bloodfin tetra (Aphyocharax anisitsi)
They are of peaceful temperament and omnivorous by nature. They thrive well in a tank temperature of 72 to 78 degrees Fahrenheit. The water should have a PH of 6 to 7.5.
Can fish die if the water is too warm?
Warm water causes the biggest issues, typically once temperatures exceed 90°F (32°C). Your fish breathe by drawing oxygen out of the water. … Just one problem – warm water actually holds less oxygen than cooler water. In severe cases, there won’t be enough oxygen to go around, and your fish can suffocate.
Do the fish get thirsty?

Can a fish survive in hot water?
Many, but not all, fish kills in the summer result from low concentrations of dissolved oxygen in the water. Fish, like all other complex life forms, need oxygen to survive. … Warm water holds less dissolved oxygen than cold water, so summer is the time when fish can have a hard time getting enough oxygen.
Can goldfish freeze and come back to life?
No, goldfish cannot freeze and come back to life. … There are other fish that can survive after being frozen, but these fish are specifically cold-water fish, and their genetic make-up is very different from goldfish.
What is the highest temperature a goldfish can live in?
Is this really a true description? Although goldfish can live in temperatures as high as 30 degrees centigrade, experts recommend keeping them in water that’s between 23 and 24 degrees.
