He wants out, he is bored.
Drop his feeder fish in the water so he gets exercise and protein from the fish meat and calcium from the bones..Some helpful info:
I have had my 2 slider girls for 36 yrs. The bigger the environment the bigger the healthier the turtle. Remember 10 gallons for every inch of turtle. I have used kiddy pools and plastic pond liners from most nurseries and worked great.
Did you know that they need to bask under a reptile light UVA/UVB for 8 to 10 hrs a day for the vitamin D that they need to grow. So that means getting a turtle dock also.
Leave the heater on 75 to 78 degrees always. These turtles in captivity do not hibernate, their eating may slow down some but they will not hibernate.
Their water needs to be clean otherwise they get sick easily from dirty water cause they poop a lot.
Total Body length: 5-8" average, up to 12 inches max. Life span: 15-25+ years.
Males have the longer front nails and are used in mating. And are considered mature at about 5 yrs old. You can’t start sexing till about 3” across.
You need a good filter system! Gravel larger than they can swallow.
You need to feed them feeder guppies, goldfish or minnows for protein and calcium daily drop 20 or so in the tanks and watch them disappear in a few days! When I got these two 36 yrs ago all we had in back then were goldfish to feed , so after 36 yrs and still going strong. They can eat goldfish!
This way when they swim for their dinner they get exercise also!
I spend about 175.00 a month on fish ,goldfish and minnows. An Extra 75.00 on leafy greens and dried cubed tubiflex worms.
They sleep at the bottom of rivers, streams. lakes or ponds or your tank to avoid predators like coyotes, foxes, owls, hawks, possums, raccoons and even some wide mouth bass.
TOSS in a bird cuttle bone in the water for calcium. it will dissolve real slow and if they eat it that’s fine!!
They can have garden worms, meal worms, snails, crickets, flies, crayfish small frogs, dragon flies and anything that moves, but only as a treat.
They need leafy greens Romaine, Butter lettuce. (Iceberg and cabbage are bad for them, any other leafy greens will do) for vitamin A that they need at least 3 to 4 times a week.
You probably already know that they get sick easily, shell rot, respiratory sickness, lopsided swimming, coughing, blowing bubbles from their nose.
**Swollen cloudy eyes means lacking in Vitamin A. Which we all need for good eyes. Google ‘vegetables with Vitamin A.
