it depends on how big your terrapins are. if they are small little terrapins, about 0.6m x 0.4 plastic "tank" is enough. if its very big, you should give them freedom and let them walk at home WHEN YOU ARE AROUND. or else they will run away.
Crayfish are scavengers, den builders and roamers, It really depends on the species, Male crayfish will most commonly attach and kill smaller males if there is not enough room for them both to make a den, A 30 gallon tank supports a single crayfish, there was one other but as the one grew it became more aggressive and ate the other, taking over the entire bottom of the tank, while in a 20 gallon tank I have2 that are both dwarfed and will have territory wars
This being said it is really not recommended to have more then 1 crayfish per 3-6 feet of tank bottom, Unless you can provide plenty of hiding places and a substrate they can move around to suit their wants and needs.
That is a good question if you want to find that out you should go to Yahoo answers.com a lot of people there know about turtles you just might find your answer there
SEA TURTLES... think!
What kind of turtle is it? Turtles like painted turtles and slider turtles should be fine. But turtles like musk, mud, or soft shell turtles would have trouble reaching the surface to breath. Do some research on your turtle and find out what their habitat should be. Deep or shallow.
I have mine together in the same tank and they are fine so I don't see why not.
how long do mud turtles live?
Yes adult mud turtles are often hunted by alligators.
Musk and Mud turtles can be found anywhere from eastern and southern USA to Argentina.
yes
Mud turtles are Semi-Aquatic turtles. Even though they spend much more of their time in the water compared to Sliders, Painted and Map turtles, they do come out on land to bask or to travel to a new area.
no turtles do not hibernate in mud I think I would look it up in case I might be wrong but I don't think they do
I have a mud turtle and I've had her for about 8 years. She lives in a tank of mostly water with a small spot for her to get out under a heat lamp. She does like to get under things sometimes (when she was younger I'd find her buried under the rocks) so they do like to hide sometimes but no they don't have to live in the mud.
no and yes
Tortoises, box turtles and mud turtles are all found in deserts of North America.
yes, they are. although I would not recommend turtles as a good kid pet anyway. if you are going to give your child a turtle, mud turtles are a good beginner turtle. as are box turtles. I have three turtles, a mud turtle, a box turtle, and a spotted turtle, and I am 13. Although it is also a question of how responsible you or your child is.
