do tropical fish need a heater in there tank?

Answer 1

If your houses normal temp is colder then what they need then yes they need a heater.

Answer 2

Not necessarily, but it depends how cold it is in your house, and if the fish is sick.Average temperature should be about 65 -75 degrees. Get a cheap thermometer from wal-mart or petstore & keep it in the "green" zone then you'll use common sense to decide if a heater is needed.Too hot or too cold can cause a host of sicknesses!!!

Answer 3

They come from tropical waters so unless your house is about 80 degrees, then yes they need a heater.

Visitherm (from Underworld) heaters are very good, as are the ones from Jager (part of the Eheim group). Avoid cheap, unbranded heaters. The chances are that these will be of very poor quality and will probably break within a few months.
