When I introduced my young razorback musk into my 75 gallon tank (Home of a 6 inch male black belt cichlid, 2 geophagus sp. red head tapajos and 1 yearling southern painted turtle who I've kept with other turtle before with 0 problems) but when I introduced the young razor, my southern painted kept trying to kill it! My razorback is currently in my 30 gallon planted and forced me to remove all the other plants besides the hornwort and anubias as I don't want him to eat any. The razorback is healthy and no damage to the tail or legs but I want to know if there's a good way to introduce the turtle back into the 75 gallon. I will move both of these turtles into my 240 gallon once they get to adult size.
