I have a RES 25 years old
I have a RES that is frankly older than I am. First of all, I don't know if it is male or female, anyway to tell? Secondly, It is been in a 10 gallon tank all its life. All I have in the tank is water and a rock that does notbreak the surface of the water by a good three inches. Basically the turtle has been in a total aquatic environment for over 20 years. In the last 3 summers, I have put the turtle outside in a rabbit cage with a pool of water and many rocks. THe turtle loves to bask in the sun during the summer. and seems to like being out of the water. I was suprised to read about the tank size requirments as my RES is about 9 inches long and has always been in a 20 gallon tank. Is it cruel to keep the turtle in a tank this small? Also, I have never even used a filter in the turtle's tank. Nor have I ever checked the water temp. When the tank gets dirty I take the turtle out, put it in the shower and use tap water (which incidentally is well water that has gone through a water softener to remove minerals) to fill the tank about 1/3 full. I never pay attention to water temp. Sometimes I forget to feed the turtle for a few days and the utrle doesnt seem to miss a beat. I have never had any health problems, never had to put any money into the turtle, and it is worrying me that there are all these tank specs I never knew about. Should I change or if it aint broke don't fix it. Also, the turtle loves to eat live flies floating in the water ( I catch them from the window and throw them in the tank). Is it ok for the turtle to eat live flies? Any thoughts out there?
