Nothing a strong one...
A 5 inch sized turtle is too big for a gallon sized tank. They need more room to swim and the filtration needs more water than that for a turtle that size. I have a 5 inch male red eared slider in a 29 gallon aquarium and I consider that to be the smallest tank I would recommend.
You can if the tank is very small. Most turtle owners opt for larger tanks, and they add filtration systems. This minimizes water changes.
no it does not
ALL fish need filtration.
Try to get it, 3 times bigger than your turtle. I have a not so little red eared turtle and i keep it in a large tank.
It depends what kind of turtle it is.Some turtles do not need water and can be kept in a room,or big area.
You need somethink like a hampster tank With Big Rocks and Water in a container the turtle can suck on also need turtle food im not sure where you can get it but try Rite Aid
You only need one that your turtle can swim in and if you get one to big it is okay they adapt to there inviorment
To change a turtle's tank, first, remove the turtle and place it in a temporary container with some of its water. Next, drain the tank, scrubbing the surfaces with a non-toxic aquarium safe cleaner or a mixture of vinegar and water to remove algae and debris. Rinse thoroughly, refill the tank with clean, dechlorinated water, and ensure the temperature and filtration system are set up before returning the turtle to its habitat. Finally, add any necessary decorations or substrate back into the tank.
A Mississippi Mud Turtle is a Semi-Aquatic turtle and as such, it will breathe not only from it's mouth, but needs to have adequate filtration in its tank so that way it can breathe subcutaneously, that is, through their skin (like a frog does) when it is sleeping in the water at night. But mostly, it breathes through its mouth.
around 80 degrees.
