I need some advice regarding an aquatic turtle -- looks like a slider to me -- that is being kept in my son's kindergarten class. His conditions are disgusting and I have found a local realtor willing to donate equipment for his proper care. My question is, what do I need? He is 4-5 inches long. I know he needs a bigger tank because they have him in a glass aquarium only twice his size. There is no water filter and no UV lightsource. No place he can get out of the nasty poop-filled water. I need a real low maintenance set-up because otherwise I have the feeling they will let everything go back to the way it is now as soon as my boy goes on to 1st grade and I stop bugging them. It makes me sick to look at the poor thing. I need specific advice and product recommendations. Also food recommendations. I believe all he gets is reptomin. I keep box turtles and desert tortoises, so I have some clue, but don't know specifically what a water turtle needs. Thank you!
