Reptiles/Red Eared Slider (Turtle)


Hi, I am concerned about my RES. (he is 9 years old) I tried to do some research online and cannot seem to find an answer to my question. My turtle has been pooping string like, brown things into his tank. They are not breaking up into the water. I have recently switched his food. I have only had him a few months now and the strings were always there and i had assumed they were his poop. However, now there is a large increase in the amount of strings on the bottom of his tank. I was wondering if the brown, strings could just be his poop and if it is normal/healthy or not? Thank you in advance!

Hi, Kellie,
That sounds unusual.  I recommend taking a sample in with him to a vet.  (You can use a turkey baster or something to collect the suspicious feces).
Since internal parasites are a potential problem, it's not something to leave to chance.  Normal turtle feces are brown, but they're not really string-like - they're about the shape you would expect.  Turtles will also produce urates, a chalky white substance (like bird droppings - they also produce urates).

My particular focus is on snakes and lizards, but I have a decent smattering of knowledge of turtles and crocodilians as well, plus the experience to get relevant information quickly if I don't have it on hand in my brain. I can answer questions on captive care, diet, breeding, incubation of eggs, starting hatchlings, and more. I am particularly experienced with ball pythons, Lygodactylus geckos and other small lizards with similar care requirements, leopard geckos, and garter snakes.


I am a professional breeder of ball python morphs, Lygodactylus (dwarf) geckos, and mourning geckos. I have begun working with Irian Jaya carpet pythons, and plan to expand to include more gecko species in the future. I also have a background breeding leopard geckos, and have kept several other species of small lizards, snakes, and a water turtle.
