My beardie is now approximately 10 months old. Ive had him for about 6 months. He has always been very timid, never bit, never hissed. Handled frequently, usually once a day, occasionally once every other day. The past week or so we can hear him hiss when we pick him out his viv or pass between handlers. It doesn't seem aggressive, more slightly annoyed. If you aren't paying attention it'd be difficult to hear. No inflating beards or black beards or any other sign of aggression.
If there isn't a black beard or wide open mouth it may just be mild annoyance. Has anything changed in his routine or handling frequency? At 10 months he may be starting in on his teenage phase which may have him a bit moodier than usual for a bit.
No changes at all, he just seems grumpier. He has always been incredibly timid so could it be he is finally relaxing so feels more confident in asserting himself?
That's another possibility. Has his appetite or weight changed recently? If not, that's a good sign. As they get used to their environment they tend to calm down. That's what's making me think it may be hormonal.
His weight hasn't changed at all. He doesn't eat as much as he used to when he was younger but that's natural at this age isn't it? He used to eat 20 large locusts a day, now it's 10 a day. He is doing a fair bit of glass surfing at the minute but I think that's just cause it's mating season for him
Yeah the decrease in appetite is normal. It's good that his weight is stable. I'm guessing it's hormonal and nothing to worry about. Not much you can do except wait it out in that case.
