Should I be worried

I may just be overly protective of my little guy but I have had him for about 3 months and never really see any droppings when I clean his tank. I have had him on newspaper for the last couple weeks and just yesterday put aspen in cool side for his tank but I still yet to see any droppings. Should I be concerned?

you could give him a nice lukewarm soak for 10 to 20 and see if it helps. otherwise he might just be a slow to dump kinda guy

I wouldnt worry too much unless it persists. My guy usually does his thing every two weeks but like Moriar said you can always give him a lukewarm soak and that should stimulate the process.
