You can, but you should probably make sure you have it at the right temperature for them. I'd say just get it back to the temperature...(Could take a while) them put them in.
Condensation.
It's probably gasy, or flatulent. Try changing to another feed.
it depends on what type of fish.a goldfish has to be in room temperature water.
I don't know if it is normal or not, but my sister had goldfish that would jump out of their tank when she would walk into the room. She would have to scoop them up and put them back in.
Condensing is the process of changing water vapour to liquid water.
Goldfish usually do not eat their own feces; sometimes they confuse it with food, but they will normally spit it right back out. It won't harm them since it's basically the byproduct of the food you feed them, but make sure you are cleaning your tank every week with a water change to remove all the waste.
Goldfish jump out of the water for a variety of different reasons. Some gold fish need more oxygen than what is in their water for example.
Ice melting back into water.
Water vapor turning into water is a gas changing into a liquid. This process is known as condensation.
If it does that it's dead
The snack that smiles back
Actually No, a Goldfish cannot swim back up the toilet. The construction of the trap (the "hole" in the bottom of the fixture) prevents water from backing up into the toilet (see links for a picture). the only way this might be possible is if the toilet is clogged. (the water can't go down the drain and overflows)
