At first i had only one Masked Julie with 2 Altolamprologus Calvus. Then i read that the Masked Julie should shared his pile of stones with another fish, so i bought a new one. But since i put the new fish in the tank, the old one push him away to the corner of the tank. I tried to make a small cave but no joy. I even cought the old M.Julie and kept it separated from the tank from 6 hours, ehile i changed all the view of the tank. As soon as i put it back, it started again picking on the new one. Do you have any suggestions? Should i just leave the old one and bring back the new M.Julie to the shop? I hope you guys can help me... Cheers Andricia23 2009-10-06 http://forum.aqua-fish.net/?topic=masked-julie-aggressive#2 The original Julie is definately at the top of the pecking order. Try taking the Julie out of the tank for a couple of weeks until the new fish settles and then put it back. mickey 2009-10-09
