ok i have given away a pink kising gourami that is about five inches long and he is currently in a fiftyfive gallon all by himself ..its my father in laws ...should we send him to the lfs ...my fil wants to go back to fresh water fish but is doing me a favor by housing this guy temporarily ..i know he still needs a bigger tank ..i had him in a 150 with a couple of blue gouramis ..one is the same size as him and the others were smaller he killed them all and i took the tank down ..what do i do with this guy? ...hes to mean to be housed in any of my tanks and i am not going to run a 150 just for him....any suggestions or tank mates that he cant/wont kill?
