How long will tropical fish live without heat?

Answer 1

no, tropical are used to living in the much warmer water than regular fish so there for if there water temperature is suddenly changed it will send them into shock and they will die.

P.S.

plese message me with a responce to my answer on my message board thank you come again

Answer 2

Without light the water will eventually go putrid from plant decay and other factors, and the fish will die if nothing is done to correct the problem and provide suitable light. The length of time the fish will last in the dark, bares a direct relationship to the size of tank, stocking rate, size and species of fish and many other factors.

Answer 3

This will vary by how cold the tank is allowed to get, and what kind of fish they are. If the water is allowed to go much below 65F, most tropical fish will not survive very long (a few days perhaps). There are a number of more hardy tropicals that will survive in the low 70's indefinately, whereas others will succumb to stress induced diseases (notably, fungal infections) after prolonged temperature stress.

Answer 4

Well, I have a gold fish that lived without a heater more than 5 years, so I think that most of gold fishes can live without a heater, although my fish tank is near my radiator for few months now. :)

Answer 5

Species dependant. Between 6-7 months to several hundred years.

Answer 6

That all depends on the room temperature they are in.

Answer 7
