just wanted to get your guys opinions on this guy, couldn't really find much information on them other then that the red ones are the hardiest out of all the linkias. when i put him in the tank he was moving around exploring no problem, and then all day today he kind of hung out on a rock. are these guys nocturnal? will he become more active as he adjusts to the tank. the tanks over a year old so should be mature enough to keep him happy for awhile. thanks guys
