Black Colouring on the tongue- Please Help

[GretaIncoll98]

Hi everyone,
I've recently got two Hermann's tortoises , and I've recently realised they've developed a black colouring on their tongue, they both have healthy diets and only one treat of a little lettuce or cucumber, I'm worried and I'm really needing help thanks,

Once, my hermanns had a browny black tongue one morning and it freaked me a little (again she has a great diet) .... Once she had eaten again it cleaned off (thank goodness) and it's not happened again yet.....

The tortoise might have been eating poop.

it appears and goes and reappears again, and unless I missed a few I don't think they have been eating their poop xxx

They're probably mixed with Chow Chows
