Something wrong with his legs...?

[Aimee]

Hi everyone. I really hope someone can help me out...

For the past two days I've noticed one of my african dwarfies holding his hind legs in a way that looks quite unnatural. The knee joints seems to be deformed/disfigured in that instead of forming a smooth angle between the femur and tibiofibula, they are kiltered up, resulting in the tibiofibula sitting directly above the femur...like his knees are bending the wrong way

His movements seem normal and unhindered...it's just when he's sitting still that this happens.

He also seems slightly lethargic, not showing much interest during feeding time.

Diet consists primarily of frozen bloodworms with occasional brine shrimp or algae waffer. I try mixing commercial frog pellets in each feeding, but I've never actually seen any (I have 5 frogs total) successfuly eat any.

Could this be metabolic bone disease brought on from a lack of calcium in the diet?

Water parameters are fine: 0 ammonia, 0 nitrite, 20-40 nitrate, temp of 74-80 F

What do you guys think? He really doesn't seem very happy...

I tried to attach some photos...sorry they aren't very good quality

I'm truly sorry that this hasn't been answered. Hope that things are okay with your froggie. My guess would be metabolic disorder. Wish that I could help more.
