well dont have the frys nemore i fed them to my JD and male con. i reintroduced my pair of JB cons to the main tank and took out my 3 groumies and got rid of my angel fish. i have all the lights off right now cause my JD isnt taking the new occupents to well.
He never will, the tank is to small for him alone and from the sounds of it he's started to claim territory plus you feed him live foods which tends to bring out aggression.
Get rid of him before he's all you have left, especially if you want to keep the JBs.
the jbs are back in the 5 tell i get the 14 for them ( was gonna get the 20 long but the stand isnt big enuf only 27 inches and the 20 long is 30 inches.
