My turtle is not eating
Is the temperature of the tank warm enough?
If turtles get too cold, they don’t eat as much and start thinking about their long winters nap.
Does your turtle like the food you are offering?
Some turtles, like humans, are very picky eaters. They have their favorites and their not so favorites. Start off with their favorite foods first, then slowly introduce other menu items.
Is your turtle under any stress? Are they being handled too much, traveling lately, or do they have new tank mates?
Many new animals often experience this stress and it may cause them to not eat properly. Just keep trying and have lots of patience. They may take several weeks before they eat again.
Your turtle not eating may also be a sign of illness.
