How often should you feed aquatic turtles?

You can feed your turtle twice a day, once a day, every other day, or even every two or three days. The only rule about feeding aquatic turtles is that you are only supposed to feed them however much they can eat in a few minutes (like, 5 minutes).

So, if you choose to feed the turtle only every other day, or every two or three days, then you will need to give it larger feedings. If you choose to feed it twice a day, or once a day, then the amount of food you give for each feeding should be much smaller.

I have a 2 year-old red-eared slider. I used to feed her about 50 pieces of food a day (50 of those Reptomin floating food sticks). Now I only feed her every two or three days, so I give her 130 pieces of food per serving.

Keep in mind that turtles never stop growing, because they can't get fat. If a turtle got fat, it wouldn't be able to fit in its shell. And turtles are not like hermit crabs: they can't leave their shell and find a new one. So, the shell has to grow with the turtle. Consequently, if you routinely overfeed your turtle, it will just keep growing bigger and bigger.

As I said, you are only supposed to feed a turtle however much it can eat in a few minutes. So, if there are always leftovers floating around the tank after the feeding, then you are feeding the turtle too much.
