Yes it's biology, though after talking to him I can see that he does love his animals, I don't know if it's visible in the picture but there is a window right next to the tank not on the sun side but is decent ventilation. The animal was given to him several years ago we geuss the age of the tort is around 7yrs. But it is not for use of biology he only has it bc the original owners impulse bought it relised it was too much and couldn't find a different owner, he already had turtles so thought it would be a fun class pet.Looks like it is the chemistry lab at school, so must get some bad air when they are experimenting chemistry.
