I've recently rescued a 25+ year old male red eared slider (called Tiny) form a neighbor who never cared for this guy properly. I'm still surprised that he's even alive and in a quite decent shape after all he's been through.
He spent half of his life in a small plastic tank, in shallow and dirty water (not even enough to cover his whole shell) without a place to bask, without any heat or UVB source and was only fed pellets. His growth was stunted too.
When I visited the neighbor 8 years ago, I asked her if she would allow me to give the poor guy a proper home, but she wouldn't have it. Tiny had signs of shell rot, his shell was discolored and soft on some places. I wanted to help her buy a proper tank, but she didn't want it. So I bought her the largest plastic tub I could find, a filter, lights and a basking platform. And gave her instructions on how to care for the poor guy. She promised she'll do everything I asked her.
After all these years, when I came back, I discovered that she didn't use the lights or the filter. She was changing Tiny's water maybe once every 14 days, he was living in his own filth. Water level only high enough to cover him. He never ate anything else than the pellets.
He did grow in size a lot. His shell now measures 8 inches (20cm). I guess he finally had a space to grow.
For the last year she kept him in her basement, without windows or any heat source. She did turn on the light for him a few hours every day (when she didn't forget).
Since his water was so incredibly dirty, Tiny spent a lot of time on the dock, drying himself. So I think the dirty water actually helped him to survive and heal the shell rot, because he was spending so much time outside.
A few weeks ago, when I found out she was being hospitalized, I asked her family if I can adopt the poor guy and they finally agreed!
I've bought him a large (300l) tank, heat lamp, UVB lamp, set up a great basking area, heavy duty filter (suitable for a 600l tank), he has plenty of water to swim in and he seems very happy and active now. He has started eating vegetables and lettuce. He's basking a lot and is even sleeping outside of water during the night.
So here are my questions:
- in the past few days his scutes are coming off incredibly fast - but the shell underneath seems healthy to me. I think this is quite normal, after all these years (he might even have a scute build-up), but I just wanted to make sure.
- he has a lot of white marks on his shell, and some look like they are rust-colored. They have an reddish-orange parts on them. The shell is hard and looks shiny, despite those marks. It doesn't smell or scrape off. Are those old shell rot scars or maybe signs of calcium deficiency?
- how can I make sure he gets enough calcium and vitamins? I have placed a few bits of cuttlefish bone in his tank, but he's not interested. What other foods should I give him, considering his history and age? I know he should eat less proteins and more fresh vegetables, but is there anything specific I can try? I've offered him his usual pellets, but he only eats one or two and just isn't interested in them anymore (no wonder, after all these years).
- here's today's photo of a (completely dry) Tiny on his basking area (he loves to watch himself in the mirror):

Do you see the rusty looking marks? And white marks? When the scute on that area fell off, the white part was almost completely transparent, like glass. There's also a small hole near the edge of his carapace, but it looks like a very old injury (not sure how or where he got it).
I think otherwise he's looking pretty amazing, considering everything he's been through. The red color of his neck in more orange than red though. Not sure if this will change over time or not.
Thanks everyone for your help.
