:I have what I think is a Eastern Spiny Softshell.I wonder if I need to put a basking rock inside its tank.Any information??Thanks in advance!!
Softshells do indeed bask, in fact in my experience they are more inclined to bask than many other species. Part of the reason that this is not obvious is that they usually do so on mud banks or lower parts of logs rather than piling up like sliders do.
It is necessary that they be allowed to bask - They also need a full spectrum / UV light for D3 / calcium metabolism as well. Set up the basking area with a light to warm it to about 95 degrees F (35 degrees C)
There is a general care sheet for softshells at the link below in the Care Sheets section.
