I'm a fairly new ball python owner, and have been lurking here for a while. I've read many of the threads regarding the proper way to set up your tank; and after realizing my mistakes I now have two UTH's on dimmers for the time being, and the Accurite thermometer/hydrogromter (mod in the sticky complete). My question is this.....I set up the water bowl in the middle with hides on boths sides (one hot and one warm), the second hide I bought was the same size but a slightly darker color; more brownish the original is more of tan color. After arranging the tank, I put the original hide on the opposite side it was originally one. When I put him/her back in he/she went directly to the original hide. I've read that they cannot see certain colors but can they tell the difference between brown and tan...........? Thanks in advance for your answers!
