I fed whiskey like 2 days ago after he ate and had the fuzzy down good i put him back in his tank.. I went to change his water an the lil butt head gave me a tail rattle.. that is the first time I have seen any aggression expressed from him... Now I havent fooled with him much during the winter cuz its cold in my house and I didnt want his body temp to change to much and fast... so do you think I ruined him or was it just cuz he just ate? he never did me that before
