Looks great.
The belly crawler would likely do well with some hydrotherapy. It worked great for my rescue that was a belly crawler. Learned it many years ago from Yvonne
Send an email telling them all that is wrong. Reposting and doing nothing to help or at least educate doesn't help the poor tortoise.
If everyone that sees that post that has a clue of proper care would send an email, the idiot might actually find a rescue or do better by it at least until...
My cousin and I, years ago, both work at a vets office, two different vets. Plus I used to work be a dog groomer and a dog and cat boarding facility manager. Between the two of us, we saw lots of cats. One actually was a male calico, a client of the vet my cousin worked for. Never saw or heard...
Yes, calicos are female. Very rare for one to be a male.
They must feel you and your home is a safe place for them. Some food and fresh water daily would help them and in return they will help keep varmits under control. Especially the female, they are better hunters than males.
If you're in an apartment now, how are you keeping the turtles you already have? Red ear red sliders get very big and need a pond as juniors and adults. The stripe neck get about 8 inches as adults, the Red Ear much bigger.
Any smaller tortoise like a Russian tortoise needs a minimum of a 4x8...
A lot of tortoises can swim. Best to let him do it with being on a bowl as many will just sit there doing nothing. That's are tortoises are weighed. Put a bucket or bowl, depending on tortoise size on a scale and tortoise on top of the bucket or bowl. This keeps them from scrambling away, but...
Yes, the constant swimming will help build muscle and strength. Don't need a bowl under them. The point is for them to keep moving. Always supervise and give him breaks a couple times during Do it at least once a day for 20-30 minute each. It's not going to be a quick fix, but it did work...
They don't need anything under them! I have actually done this myself years ago. Learned it from Yvonne. You want the water deep enough they can't touch and keep them moving. The point is to get them to keep moving and when they come to a side they kinda struggle a little to get out and they...
As for the therapy, place in a tub of water deep enough he can't touch the bottom and let him swim. Be by his side, never leaving him alone and if he seems to sink, place a couple fingers under him to hold him up and make him swim. I did this years ago on a leopard that could walk very good...
They will eat/graze throughout the day, likely resting during the hottest parts of the day.
As for the ants eating before her, set her by the food when you put it out.
