I have moved 3 electric blue acara in to a 120 x40 x50 cm tank I want to soon move my proteus pike into this than was wondring if he would be very aggressive in this tank I know many would say try and see. But I know if I put the pike in there and then have to remove him I dont think I would ever get him out as the than is very heavily planted and there are so many nooks and crannies it would be impossible to get him out without draining the tank he is in an 88 lt tank at the moment and is pushing 4 inches had him 4 months so some opinions please before I do it.
