hi i kept 1 think it was about 2years ago and he never left my 2 royals alone.they were always covered in bite marks. had 2 end up putting him in a tank on his own.
as for escaping i woke up 1 morning looked up from bed 2 see an empty tank,didn't think nothing of it, thought he was just hiding in plants wasn't till i started hearing a banging coming from tank area went over to check it out there he was lying down back of tank with no wiskers and coverd in carpet burns put him back in tank he was back to normal within a couple of days.dont know how long he was down there could have been anything upto 8 hours.
he was about 20" long killed lots of my fish,would i have another 1 show me where i can get 1
