I had a Herman tortoise with many pinworms. I was given liquid medicine, and I put it on his food. He had his treatments. Then I brought a fecal sample back and he was fine. I'm not an expert however that doesn't seem correct for moderate pinworms. @zovick @Yvonne G can help
I started to reply, the growth lines were different. Thank you for answering me. Still a very nice looking tortoise. Also, when I got Ink I don't know if mazuri was available (dial up connection times), I used chicken feed for hens laying eggs. Another vet told me that and works great.
I give mazuri maybe 2 times a month and only a few, and he is almost 18yrs old. I personally would do more greens and Google Kapidolo Farms for organic options. They are awesome and very helpful. @Kapidolo Farms
I would try to clean the substrate up and clean the eyes today. I'm not an expert but that is my opinion. @Yvonne G @wellington or @ZEROPILOT can help you more.
What lights are you using, temperature, enclosure and substrate? Can you post a picture of the enclosure and the tortoise? It would be very helpful. Welcome to the forum. @zolasmum can help too.
