I was just taking my normal BP out of the tank when i noticed a small bug on the glass I then moved around the substrate and noticed some of these bugs moving around now i remember back when i was alot younger 13 years old I had an iguana with mites they were red and black the bugs in the tank were weird I currently reside in my grandmothers basement for another 2 months and im not sure if the bugs are from the basement and they are just taking up residency in the substrate or are they mites. I checked my snake and didnt see anything on him I also checked my other tank where my other two babys are and there is nothing on there. Maybe i need to just clean the tank out. the substrate i use now is jungle bark something like Exo Terra makes it someone help me out
