Right now I have 4 cockatoos in a 75 gal. tank, but I wanted to add 1 pair of kribensis. My question is, with a about 5' long tank, and like 6 caves, will they be able to get along? Also, after the kribensis spawn, my plan was to remove them and place them in a refugium on the side of the tank with the cave full of eggs and the mom, possibly the dad, but only after the eggs were laid, so they wouldn't be able to take out their anger on anyone. Does this sound like it could work? They person I would get them from said they were fine with her guppies and endlers, not to say that's what I would keep them with, so I don't think they're terriblly aggressive. Tell me what you think! Thanks!
