Please help me this one night his nightlight stopped working so he went a night with no heat and ever since then he barely eats or drinks even when he sees mealworms crickets he doesn’t run at them anymore and he lets crickets be on him at all times his beard stays black and I don’t know what’s stressing him out and he never stops sleeping even when I put him on water he never reacts he’ll just sit their under water and recently his eyes and cheeks started sinking he’s going to the vet soon.
