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.
Yes they will die because tropical fish are kept in an aquarium with heat control for the temperature of the water, they will not survive in cold water. Put a tropical fish in cold water it's metabolism will slow down to the point its body no longer works, it won't be able to digest food, will become very lethargic, and die.
Yes u can, they would actually thrive!
None, goldfish are cold water fish, so having a tropical fish as a tank-mate just wouldn't work because tropical fish need to live in warm water.
You can not put tropical fish in coldwayter bevause they need hot water to survive but you can put goldfish in coldwater becaue they are coldwater fish
You would not put tropical fish in a tank of cold water because the live in warm climates and need a temperature of 24 - 26/28 degrees Celsius to survive.
No, goldfish are best with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, and apple/mystery snails.Although goldfish can survive in warmer water temperatures, they are a "cold water" fish and not a tropical fish.
Goldfish are cold water fish while the others are tropical, so no they won't as depending on what type of tank you put them in, one group will die.
I wouldn't recommend it because the fish are used to a warm temperature and a sudden change in the temperature is too much for tropical fish so they most likely would end up dead
Guppies are tropical fish. Goldfish are coldwater fish. If you keep them together one species must inevitably be being kept in conditions that do not suit it. So. Yes you can put them together but when one or the other dies it's your fault.
It is better for the fish to be put in water that it was found in.
NO do not put tropical and marine fish together because marine fish have salt water that has to have specific things in it other Wise they will die .but tropical fish just have to have warm water with a heater .you cant mix these together because of the water and ALL your fish will DIE.
Yes, it is bad to put tropical fish in with river fish. The river fish can make the tropical fish sick.
