Yes they are. Plenty of websites will give advice.
White Cloud Mountain Minnows (Tanichthys albonubes) are a TROPICAL fish and should be kept at around 64F to 75F. Although they are very tough and can stand being kept in cold water conditions their life span is greatly reduced by being kept at too cold temperatures. They are egg layers and so can not get pregnant.
betas, white cloud minnows, small cleaning shrimp, maybe even a goldfish for a few weeks before it out grows the bowl.
For a short while. They are an active, cold water fish that require plenty of room and cool oxygenated water. That's difficult to achieve in a one gallon container. A five gallon aquarium would be much better, with at least ten gallons being preferred.
a cold, high altitude cloud
Fish are cold blooded.
goldfish, sometimes minnows and even sometimes guppies and bettas but it depends on the range of temperature
since it's cold outside and the water is warm the water turns into steam
The water vapor in your exhaled breath condenses- it goes from very warm to very cold. The drop in temperature makes the VERY moist exhaled breath condense into water droplets. Those water droplets are visible, just as a cloud is visible.
When you breath out, you breath out some water vapour. This is normally invisible, but cold air cannot hold as much water vapour compared with warm. This causes some of the water vapour to condense in mid air in front of you, forming 'the cloud'!
You can put some but not all cold water fish in tropical tanks for example you can put zebra danios and mountain minnows with tropical if you gradually increase the heat. You cannot do this with goldfish. It depends what fish you have.
first it evaporates into a cloud, then its held up in the cloud for a time and when cold and warm air mix it comes back down to earth.
Because the cold air around you cannot hold as much water as warm air in your breath, the moisture in your breath condenses when it hits the cold air and forms into a little cloud.
