Hello,
Hello,
The rule of thumb for these turtles are at least ten gallons per turtle of water. From what you have stated the tank is too small for your turtles, You should have at least a 10 gallon tank per turtle. The Temp may be a little low for your turtle. The sick turtle needs to be isolated. You should have a good filtration system on the tank and the turtles need a good basking area as well as a UVB light source to help simulate the natural sunlight. Your Diet needs changing.The diet should be 50% green veggies, 25% prepared food and 25% meat. This turtle will need some antibiotics from the Vet. Since it seems to have a Respiratory infection which could be because or the lack of proper filtration, temps, lack of proper lighting UVB light is necessary for proper health, diet, or a combination of all these. You need to be supplying a good source of calcium for the turtles. If you can supply a city and state I can help you locate a Herp Vet. I hope this information is of help. Joan
