My beardie (who is about 3) has been glass surfing like crazy. I know it usually means stress but I don’t know what it could be. He’s in a 40 gallon and I’m saving money to get him in a bigger tank with new things. He doesn’t really like being held a lot and when he does get out of the tank he just runs to a corner and will hiss if I try to grab him.there hasn’t really been any changes for him
