How old is your turtle?
Do you use the correct temperature settings and gradients plus plenty of uvb light (at least a 5%tube) and supplements of calcium, heathy diet etc for him. He may look a little better but if the conditions are not right he will succumb to illness in the end so you need to consistantly monitor these things.
My guess would be to research what type of turtle you have and look up
-What temp the water should be?
-How much and what food to feed them?
-How much light they should be getting?
Another big one is to make sure you have a good filter system and make sure you clean the tank regulary. Ph levels may need to be changed to.
Your turtle will be in the water not moving a single bit.It wont move for days wich is why you need to feed it.
Tell A vet.
Take youre turtle to the vet
car wont turn over and anti-theft light blinks
if your box turtle is aquatic, it may be because the water is too cold or its uncomfortable in its habitat.
well ,it depends on how the catfish is acting. if it annoys the turtle or harasses it, the turtle will obviously react.
because they suck
you can put a turtle in a tank with no cover and it wont crawl out while you are sleeping
it bit you because it felt endangered
It either likes you, hates you, or can't figure out what to do.
Maybe its at its fully grown size.
it will have 1 less hand and wont swim as fast obviously
