i've been home sick for the past few days but my leos have been given water and fed while i was gone. when i came back last night i looked in their tank and noticed tiny bugs about the size of gnats in there. i use paper towels as a substrate so i could spot them pretty easily. i took everything out of the tank and wiped it down with a damp paper towel and i checked to make sure i got all the bugs. i put fresh paper towel down and thought everything would be ok but i just looked in there today and the bugs are back! i don't know if they're coming from or attracted by the damp coconut fiber in the humid hide? is that something that i have to change frequently? is it using paper towel as a substrate since it absorbs pee differently than sand or bark would? the leos are still getting out the shock of being shipped and are not ready for handling so i can't keep going in there every day to change the paper towels. my next step would be to change the coco fiber in the humid hide, but i was wondering if anyone would be able to help me out over here. should i try using a different substrate? i was just nervous about sand because i kept hearing stories about them ingesting too much and dying. please help!
