I have 2sulcatas, both of them are 3months old.
One of them has not been pooped off while being forced soak for a several weeks.
But the other one always pooped off immediately after put him in warm water.
If he has not pooped off for several week, he would be alright?
He should perk up after sunbath because of metabolism rate rised.
Try changing another diet if he wouldn't like to take.
If he start to take, remember do not force him to take a lot at once
because digestion system still hasn't worked well.
Increase volume gradually everyday...
I wish it could help, my tort is around same age when i lost him.
I would not let it happen again to your tort.
It's necessary to force him to eat gradually to recover his digestion system
which is currently full of gas after not working for a long time.
Anyway, don't forget putting him under...
I have no experiences about baby food soak, but I think it would be no problem to try.
Gently open his mount by your fingers, if he shut his mouth tightly,
then try the order below
Put him under direct morning sunlight first, to make metabolic rate rise around 30 minutes.
Then, soak him 15-20...
Welcome to the forum,
I've got very same experiences as yours, size of my baby leo was also about the same size of yours..
Your torts is very very sick..
Additionally if you noticed, some where of skin around his eyes would peel off, wouldn't it?
You should bring your torts to the vet...
