If you're worried about MBD then bring your Leo to a vet who will prescribe a liquid calcium supplement to give your Leo. Make sure you are also dusting his/her feeders every time with Calcium with D3 (no phosphorus) or a Multivitamin.
MBD can be reversed if you make sure they are getting adequate calcium.
Looks like MBD to me, but I'm not a vet. take your leo to the vet, leave a dish of calcium without D3 in his tank, dust every feeding with repashy calcium plus. Also, make sure you are gut loading all of your feeders. I feed my leo Dubia Roaches gut loaded with a mix of Fluker's High calcium cricket diet and roach chow from westcoastroaches.com. I also toss some greens and fresh fruit/veg in their bin once or twice a week. I gut load mealworms with the same thing.
