Tiko's Medical Bills

Meet my 8 month old bearded dragon Tiko. I bought him from what I thought was a reputable breeder at the time. When I got him back in October I noticed that his beard was a slight shade of grey. I shook it off as nothing because I just thought it was due to rehoming stress but it never went away. I took him to the vet to find out he had parasites (and still does because they are very hard to get rid of) so I figured maybe that was the cause of his grey/black beard and once the medicine lowers the count of the them the black beard will go away. But it still hasn't and he now has reoccurring diarrhea, occasional muscle spasms on-top of his bearding. The vet says that when they beard 24/7 it normally means something is wrong and all the symptoms he's having is not caused by the parasites. In order to figure out what is wrong with my baby I'm going to have to run different tests on him to figure out what is wrong which isn't cheap and I sadly don't have the money for and neither does my family. Any donation helps and if I have money left over after the last vet bill I'll donate it to Beautiful Bearded Dragons Reptile Rescue.
