I did not read your whole post, but it does sound that you have "DENTIST" fish...............Dentist fish are small schoolin' fish that belong in a Dentist waiting room...........If you are new to the Monter Fish hobby, I would have to suggest empyting our your aquarium's life.............Then, get a breeding pair of Convict Cichlids..................The juvenile size of this fish cost between $1 and $5..............The females have orange to red blotches on their bellies............These fish will breed within two weeks of being setup and comfortable in their new homes.............Why buy the Convict Cichlid, because this species is the basic building block of all Central and South American cichlids...........This fish has all the attitude of the big gunners, the same breeding concept of all the larger cichlids, the same basic diet of all the big cichlids, and the same care requirements of all the American cichlids..............
