Not necessarily, but if you don't want to see a bunch of poop at the bottom of the tank, I recommend that you out gravel. Don't use the colored rocks. Those are painted and release paint over time. Investment your turtle gets bigger I recommend that you switch to bigger gravel so they don't eat too many of the rocks (they eat the rocks... its weird, mine have been doing it for years, and I can't find an answer to it.) .
I wouldn't recommend it.
what will happen is that the baby false map turtle will get along with the red ear slider .B ut it will just take a will.
Yes you could if it in a big enough tank or pond.
You should keep a baby red ear slider away from other pets like dogs and cats because they are small so keep them in a good tank with maybe other baby turtles
A tank is very expensive and probably restricted to use by military personelle. You could kill a red ear slider by much more economical means.
around 80 degrees.
Nope. Rounded gravel is fine.
totally upto you. i have gravel in my bettas tank.
YES, you can put a map turtle in the same tank with a slider.
A baby red-eared slider does not need a big tank. However, turtles grow fairly quickly, so, if you buy a tiny tank, you will have to buy a larger one when the turtle grows. So, to save money, you might want to just buy a large, adult-sized tank, and let the turtle grow into it. When I first got my red-eared slider (two and a half years ago), she was only a hatchling, about the size of a silver dollar (like, an inch and a half). At first, I got her a tiny tank (see the Related Link). When she grew too big for that, I got her a tank that was 12 inches long and 10 inches wide. Then she grew too big for that, so, now she lives in a tank that is 20 inches long and 12 inches wide.
How much gravel for 200 gallon tank
Yes, they will eat any small pebbles. This may cause digestion blockages and can be FATAL. When putting gravel/pebbles into a turtle tank, make sure they are at least 2cm big.
