Just curious, but did your radiated poop out substrate that it had eaten in that one photo, or just a mucus? Can't tell if the substrate is just damp, or that's what came out.
Update 4/10/2019
After battling 8 months , he didn’t make it .
Passed away this morning .
—————————
2 days ago he pooped a large amount and weight dropped from 1291g to 987 g . He was around 980g last August when I found out the abnormal behavior.
Although he had been eating , seems no nutrition was absorbed . In 2nd picture you can see the white underlayer bone plate between the scutes . No growth at all .
Oh man! I am trying to catch up on all the threads I’ve missed out over the past couple yrs. I am so very sorry for your loss!!! Please accept my deepest condolences. You sure did what was humanely possible to your tortoise.
