hello, everyone! I have had two little tadpoles for about one week now. Based on my research, I believe they are toads. They live in one of those pet carriers with natural spring water, some rocks for hiding, and a live leafy plant for shelter, food, and oxygen. They seem to be doing well, but I am concerned about the temperature of their water. Right now, there is no need for heat or AC, and my house is about 71 degrees F. I put their tank a tiny bit in the sun later in the afternoons so they can get a little vitamin D. I am just concerned about the water being too cold. It doesn't feel like it is above 70. I am buying a thermometer today. Any advice?
