Spots look like minor wounds from scraping against something in the tank or possibly inflicted by other fish. Will heal with lot's of clean water and proper diet.
Cichlid pellets, Thawed bit's of frozen krill, fish,shrimp, chopped earthworms, freezedried crickets, and pellet foods with spirulina and or vegetable matter such as New Life Spectrum Pellet for medium to large fish.Would offer beef heart ,boodworms,sparingly.
Would resist the urge to offer store bought feeder fish which are often loaded with parasites or bacterial pathogens unknown.
With the fish you have ,, and foods being offered ,it would be very difficult to achieve 5 ppm Nitrates between weekly water changes and to keep Nitrates low,I would perform 50 percent water change each week without fail along with vaccuming the substrate(gravel).
As the fish get larger,,twice weekly water changes may be needed to keep Nitrates between 20 and 40 ppm with 20 ppm being ideal.
The
Oscar alone will require 75 gallon tank or larger ,and Bala sharks grow very large as well. Have zero expierience with Pacu's but those I have seen are often softball size and in groups of five or more, Ditto for bala sharks.
As you say you have no intention of re-homing these fish ,then plan on a tank of 200 gallons or larger with filtration suited for tank .Otherwise,,I would expect probable health issues with your present fish stock.
