we bought a 11m old SWCP about 3 weeks ago. Had been eating weekly most regularly until we received & hasn’t since. Tank on 33 & 27 on cool end (small tank 30cm so hard to make a greater gradient with light above). When should I start to worry & any tips? Have blacked in sides, in secluded area of house, don’t handle & explores more at night, although coming out to bask more lately. At a loss as had bigger snakes previously.
