He is likely starting to feel better. I would get him on as many weeds as you can and grass and add a good portion of Mazuri. Dandelions are full of calcium. And don't forget a lot of sunshine!
Outside time in the sun will be the best thing you can do for that tort. He is certainly suffering from MBD, which is reflected in how he is walking. But he will get better in time, although he will always show signs of his poor start. I am glad you have him now.
It is official. I just ordered my first 25lb bag of Mazuri. She eats enough where buying it in smaller repackaged quantities has stopped being economical.
I always chuckle when I hear someone has a fussy eater for a tortoise. Nadine's only preference appears to be toward the food that is closest to her mouth.
I would say give them away if you won't A) separate them, and B) give them a better environment with cover and humidity. Get a goldfish instead.
Sound harsh? It is. But honestly, they deserve to be well taken care of. Then research your next pet better.
Depending on the set up, the small compact bulbs may be ineffective.
As far as dangerous, I have now tested just shy of 200 used bulbs and a couple dozen new ones. NONE produced anywhere near dangerous levels of RF radiation or UV light.
Still hunting for that dangerous bulb...
I would not get sidetracked into thinking the bulb was the problem. It isn't likely at all.
What is the humidity? Looks dry in the pics. I don't like the moss setup.
