I have a 16 year old, 5kg male red foot tortoise that I’ve had for 6 years. He came from a former employer that used him for reptile shows, and as one of my show animals, I fostered him while working for this individual.
He was approximately 3.75 kg when I got him, and the enclosure he came...
Can definitely keep my girl outside during the summer but have to keep her indoors during the winter- temperatures get down to -45 c on some chilly winter days here. There’s allegedly a population of RES in a local lake but I’d be nervous with a man made pond and those temps 😅
There are some liquid calcium glubionate items, but otherwise I’m not super familiar with many reputable liquid minerals or multivitamins. Have you tried multiple brands of powdered vitamins?
Old forum, but I’ve added powder orange and powder blue isopods to my adult male redfoot’s enclosure and the dang bugs have nearly taken over all of the bottoms of surfaces. Fantastic breeding ground for them
