well after a long 15day vacation out of town i came back home and found my two emps almost dead, they didnt move at all( this happened last sunday, the house could have been as cold as 65 f), so i turned on their lights and put them near the heater, now they are better, they wont move from the warm side of the cage but it seems that all their reflex and response to anything is at a 100%, do you think they are actually healthy or is there somethin that i may not know?
