We have a small koi pond in our yard (small being relative here, it's several hundred gallons in a two tier pond) with an assortment of plants and a few bullfrogs to keep the fish company. My father ordered a pair of Red Eared Sliders (adults, ~4-5" shell length) in late March, plopping them in the pond when they arrived as the water was quite warm, along with the weather. Things went downhill from there.
So our turtles don't eat for a few days, which isn't an immediate concern as they are new to their environment. But when we didn't see them at all for several days we grew concerned and searched the pond bottom. Nothing. I searched around the pond area and found one hiding in some undergrowth. As for the other, he escaped for areas unknown (no nearby ponds either).
As the weather started getting unseasonably chilly, we took our remaining turtle inside and setup a small tank for her using a large (30-40gallons) plastic container, a few rocks from our pond for a basking area and dechlorinated water. Shortly after we took her inside we were getting temperatures below freezing as a high, which is unusual in SW Ohio. We then upgraded her to a small swimming pool with an added aquarium heater and we kept an electric heater nearby to keep the air warm. During all this time we were unsuccessful in getting her to eat. We tried the pellets, romaine lettuce, turnip greens, mustard greens, carrots, etc, with no success. Then we notice her coughing
We think that the turtle picked this up during the time she was outside, out of the safety of the pond, and coupled with two environment changes in short order, it likely just fried her ability to cope with diseases.
Provided we get another turtle, we've already built a rock fence around the pond that will prevent another escape and I'm thinking about how we might modify our indoor pool as well. We have a number of cats in the house and while they enjoyed watching the turtle, they didn't go after her or stick their paws into or near the pool. Could this have added more stress to the turtle? If so, would adding a visual barrier help calm the turtles in the pool down? We also have an extra filter we were going to add, up until the turtle died on us.
Suggestions and comments welcome, we liked the little guys, but I imagine we killed them with the impromptu nature of all this stuff going on.
