I've got 2 JDs, a male and a female pair, their only other tank mate is a RTC I am trying to get rid of. The catfish loves to hid all day(obviously) inside this pirate ship decoration I have. However my dempseys also want it(surprisingly because I built them a cave thing with a flat rock as a bottom). My RTC is has almost an inch on my cichlids and my bad ass male grabs on to his face and drags him out of the cave like its nothing. I know this isn't normal because JDs tend to be a more passive cichlid. I am proud to own to mega aggressive Jds. I can't wait until the spawn (they're a new pair and haven't done the dirty yet) so I can see how much meaner they get.
