Ok, so I have 2 large jaguar cichlids, female is 10 inches long and the male is 12 in. I also have a pair of jack dempseys, male is between 8-9 in, and the female about 7 inches. Currently they are in seperate tanks and both pairs have spawned before. Anyway, I have ordered a 240 gallon tank and was wondering if I would be able to put both pairs in the 240 together. I'm worried about the jaguars aggression towards the JD's during spawning, but also Wondering if a 240g would be large enough to not worry about that, and also if I would be able to possibly put more large fish in the tank in the future? Thanks
