Hi guys I rescued a 13" RTGG last week along with a 15" Red belly Pacu. I placed them both together in a 450g and the Pacu has beaten up the RTGG pretty badly. Then I took my RTGG out to heal and placed him in my 225g. My question is I have smaller fish in the 225 from 5"-12". Would the RTGG kill my other fish such as smaller GT's and a Frontosa? In the 225 I also have 5" NTT Datnoids and 9 x 5" Clown Loaches. I just couldn't stand the pain watching my was beautiful RTGG get torn to pieces.
