Hi! So I have read all the post and first of all I guess those are Phoenix worms and not wax worms,,lol...that's good. I am going to suggest first of all to switch to Pet Authority Brand Acidopholiz+ probiotic...it just works better for some dragons. Now,,,since the vet said he had amoebas that answered the question about the direct smear...you will need some Flagyl to treat the amoebas...please let me know what the vet says about the amoebas, surely he will want to treat seeing as how your dragon is still displaying symptoms...
