Hello!
I gave my 13 year old red ear slider couple some tomato for the first time in the season, and a little shrimp, which is a very regular for them. They ate them with big appetite, and everything was fine for 3-4 hours (they eat somewhere else than where they live). But after I took them back into their living terrarium, like 2 hour later I found the male in the bottom of the tanks, completely lifeless, and everywhere around him was undigested tomato pieces. My other one, the female is looking good, she is still active. I separated them, and I placed the ill male into a basin with water. He is just lying there, with his arms and legs are outstretched, and his head is hanging. When I touch him, he very slowly reacts, like retracts his legs. Before this incident they ate 1 week ago, shrimps and pellet. I don't think the tomato is poisoned because, the female is fine, however the male is much bigger, so it can be possible, he ate way too much tomato too fast. I tried to see if some tomato stuck in his throat but didn't see anything. [Sorry for my english]
Please help me.
