the thing is they don't sit in overly filthy conditions, it is sparkly clean, believe me but he lived in horrible conditions before i got him in april. I've been reading that a lot of protozoan are common in frogs and are not pathogenic, so no treatment is needed, I'm kinda confused and only hope vet will know what he is doing.
pacman food from tongs is not a solution, the only way i see administering orally is force feed, he is a VERY picky frog and only will take anything if you annoy him enough to open his mouth unless it is pinky and even then not right away.
