My beardie is about 4 years old and up until a couple months ago everything was great... He has had diarrhea for about 2 months... He's been to the vet twice.. parasite tests were nothing of concern.. he's been treated for giardia (probably spelled that wrong) he's not losing weight, he eats normally... I'm almost $600 in on vet visits and I don't know how much more I can afford... I recently changed his light setups to a t5 high output... I'm at a loss... Someone help...
