Yes they are. These guys have been in the same enclosure for about the last 3 years. I was not to worried about it until I came across someones post that said "they are not cuddling, they are competing for the best spot in the enclosure" after watching them this makes perfect sense. I have a 29 gal tank that I am going to empty and clean up so they have there own space. I basically took these away from a friend because he had no intrest in them. They had no heat(they do now) they had no light(they do now) they had no hiding(they do now). I am trying to educate myself as quickly as possible to give them the life style they deserve.
