In this manner, can turtles live together in the same tank?
Groups of turtles may live in the same place because the conditions there are favorable for them, but they aren't really "social" animals. But as they grow up and the turtle equivalent of puberty kicks in, turtles often start fighting (especially the males if you have more than one male in the same tank).
Additionally, how many turtles should be in tank? Turtle Necessities A 30-gallon tank is the absolute minimum size for smaller species measuring between 4 and 6 inches. For turtles between 6 and 8 inches, a 55-gallon tank is appropriate. And for turtles measuring more than 8 inches, tanks in the 75- to 125-gallon range are a better choice.
Similarly, you may ask, how big of a tank do you need for 2 turtles?
Plan on a tank size of 10 gallons of water per inch of the turtle as a general rule of thumb, with a minimum size of a 20-gallon for hatchling red-eared sliders. Keep in mind that red-eared sliders can grow to be 10 to 12 inches as adults, so it's likely that you'll eventually need a very large tank.
What can you put in a tank with a turtle?
Very small, agile fish like guppies may be able to survive with turtles, though they may overpopulate the tank. Goldfish and minnows are often kept with turtles because of their low cost; if they are eaten, they can easily and affordably be replaced.
