Hi All,
we have a 55 gal malawi tank with 3 labs, 3 jakes,3 vc-10, 4 maingano and 4 jewels a spotted cat and a pleco all about 2".... we just moved the breeding jewels out of the tank to a 'breeder tank" and we have had 2 of the female jakes die and 1 ( I believe the lesser male) Maingano getting pounded. ( he will probably be dead in the am) I believe the Jewel was the alpha and now there is a battle for it but why are all the females dying. our tank is very stable 8.2 ph 78 degrees with the nitates running at 20 and nitrites at 0. Amonia at 0 too. All the fish "appear" normal. Any thoughts... we feed them all flake food.
