On the tortI'm afraid that I can not make out any details. Was it in the substrate or on the tort?
There has been a change of behavior... lethargy, little appetite....There are a few bugs that come with the substrate. They are harmless
It's very difficult to see. I did a fair amount if googling, and it does look like a tiny spider, similar to a mite. I have no idea how the tort would have gotten it, unless he came with it and it is just now showing up.If it's a normal bug that we all get with substrate, that's not the problem.
If it's another kind of bug that attacks, feeds off of animals then it could be the problem.
I can't see anything but a dot in your pic, even when I enlarge the pic I can figure it out.
Try searching with google for substrate bugs or mites or ticks and see if you can find it.
Now as for the change your noticing. What kind of tort and how old? What are all your temps, day, night, basking? Humidity? Diet? Enclosure size? Anything else you can tell us. It's likely not the bug so if it's nof let's see if we can figure out what might be going on
Substrate: Coco and hay for now, cleaned out wood chips due to possible bugsMale Russian, I would guess about 5 yrs old. He is in a View attachment 231426
Here is his current habitat. Temos are 80 to 90 and humidity around 69 percent during the day, I've been keeping it there at night since it's been so cold here in PA and we keep the house at 66 degrees--and just turning the UVB off from 8pm to 6 am. Ceramic heat, UVB and infared. Diet: escarole, endive, dandilion greens, occasionally kale. Soaks 2-3x per week.
There were definitely more.If it is a mite, you should do a thorough check over your tort daily for about a week. If it's just one, it's not likely the problem unless your tort is very young and small. If there are more it could be a problem.
