This is an unfortunate situation. I just moved into a room in a house and I'm only here for a short time (10 weeks or so). There are two RES that have been abandoned here by their previous owner who has been negligent about retrieving them. They are both between 4.5 and 6 inches. They have no lights, their water is gross. I have no idea what/if they have been eating. One of my housemates said something about them eating the goldfish in the tank.
They have about an inch or two of water that has to be full of feces and fish guts. They probably need veterinary care, but I'm a little hesitant to start putting money into them. I'd love to clean their tank out and give them fresh water to wade in and a reasonable habitat. Is there a way I can avoid spending a lot of money and getting these turtles into a reasonable living situation for the mean time? I have no experience with turtles but am happy to learn.
Any suggestions will be greatly appreciated.
