Can't find mites what else may it be

[BryanB]

Ok Inka "BCL" is acting only a tiny weird but it bothers me. He has payed in his water twice this week but has never before he refused a rat last Monday but took 2on Thursday. Granted he is looking like he may be going into shed again " he shed 2 weeks ago " but he just isn't himself. I did change his tank out for a larger one but changed nothing just more space from a 2x3 to a 2x4 peramiters are 92degrees basking 76 cool side 50+ humidity. What should I look for I have looked in the water, surched him and wiped him down to the point I think I am just paranoid. Oh and he lives on a sand coco topsoil and perlite mix seeded with spring tales and misted 2 x a day
