In my 125 I have a ebjd and a nic both just over 4". These 2 have shared the tank for 3 month and never paid any attention to one another, however for the last 2 weeks the nic was quarantined for internal parasite treatment and now that she is healthy again I returned her to the 125 and in less than 5 minutes the ebjd had half the nic's face in his mouth and relentlessly followed her around the tank. I guess my ebjd didn't get the memo stating that he's supposed to be peaceful.
