I don't know really anything about monitors but my first guess would be that the humidity is too low and he isn't shedding all the way. The stuck shed on his toes cuts off blood flow, killing the areas that blood can't reach and causing them to fall off.


The best way to keep humidity and heat in a glass tank is to cover 2/3-3/4 of the screen top (that's what I'm guessing you have).

That's all I can say since I'm not familiar with monitor care, good luck with your sav!
