Do fish give off signs that show that they are cold..... my water always seems cold but it isn't but it seems like my fish might be cold.
Yes they are all perfect i tested them the other day w/ my friends kit.( which is very good and accurate).I agree with Rocker - get a good thermometer. Glass thermometers are really inexpensive at Petsmart or Petco. Do you know if the water is good - do you test for ammonia, nitrite, nitrate, and pH.
