with the lights off i just added a 8in. widebar to my 150 with my tem, pike cichlid, gar and ornate and immediately my tem started flaring up and mouthing him so i threw a handful of feeder minnows in to distract him it worked for a lil while but now the dat is hiding in a cave with the tem kinda waitin for him my prob is i cant move any of the structures around cause there so huge what else can i do? im thinking bout putting the tem in a cooler with a bubbler for the night but im afraid of losing him
