I totally agree with Perfectly_flawed, and second that idea. Check the care-sheet and do a fecal test.
You can also try Para-zap. Para-zap is made of 100% natural ingredients, and overdosing is not a concern. Para-zap is a food supplement, not a medicine or drug and can help with lethargy, appetite loss, and parasites and more. It's very safe and effective.
I use it as a food supplement occasionally, and dose a bit more heavily anytime I think there's a problem with one of my beardies. It's a great route to take before you try some of the more harsh medications. When using Albon or other hard medications, use Para-zap to counter the side effects, which happen to be appetite loss, and lethargy.
You can get a jar for around $20 delivered and it will last you a year or more. You make the powder into tea; and Dragons require so little of it, just a few drops.
Check it out, it's really worth taking a look at ...
