How small is too small?

[Reptilian]

oh boy, you really think he could have patasites? i did move him from tank to tank quite a bit, first it was 20 gallon, then 32 qt. then 12 qt. he is very active around the cage after i put him back in it. and sometimes a see him wondering around.

If he's eaten several meals and not gaining weight it could be parasites. I am not a herp vet though. I wouldn't be surprised though.
