i have had my pacman named sarlac for about a year and a few months and as of late he has been hiding with out surfacing for weeks on end. i do live in cleveland where we have had a terrible winter. hes in the natgeo 26 tall tank (only sold through pet smart) with a drainage layer then fiber glass mesh, 4 inches of eco earth to burrow, a 10 watt fish tank uvb compact florescent bulb, 2 25 watt incandescent bulbs, live plants of dracinea (white ribbon) and arrow plants and a zoomed reptofogger. his tank stays about 65 at night and up to 80 in the day. his humidity varies between 55 and 99%. his substrate stays just wet enough to form shapes but not so wet that if squeezed it looks like a wet cloth. he loves to hide under the roots of the plants but he refuses crickets and other prey items but eats his night crawlers or his once a month thawed pinkie or baby mouse if i dig him out of his burrow. should i worry or is he being normal for the winter months? his soak bowl is filled with reptisafe tap water and i spray the plants down with spring water and his fogger which only runs every 3 days for no more then 20min uses distilled to keep the glass clean and keep the top layer wet. if i put him in his soak bowl and walk away with out offering food he jumps out and goes back to hiding.
