I have a 3.5 inch jack Dempsey, a 3 inch red dragon zz flowerhorn(heavy trimac blood), a 2 inch jaguar cichlid, a kribensis, a 3 inch green terror, a 3 inch mayan cichlid, a 2.5 inch parrot fish and a 2.5 inch convict. the Dempsey is the biggest and roughest one in the tank he fought the g.t and the g.t looks to be blind from the fight he has cloudy eyes now, what do you guys think about me stocking all these fish , do you think one will kill off all the others? also is it good to keep my temp at around 83 to 84? do you like these fish? also I do a 50 % weekly w/c .
