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.

new 30 gallon tank

about the 30 gallon, i am definately moving my 2 paired convict cichlids to a 30 gallon, also my 1 inch common pleco (only until he reaches about 4-5 in.) would i be able to have another fish or 2 in the tank? possibly an african butterfly fish? or SA leaf fish?

that will be leaving my 55 gallon to my 4.5" oscar, 5.5" red pacu, 4" bala shark, 3.5" synodontis (still havent found out what species of synodontis, it is semi leopard spotted with large eyes and brown/yellow skin), and 2" bumblebee/hornet cichlid.

but not for long as i am looking to get a 90 gallon for the oscar and pacu, leaving my bala shark bumblebee and syno in the 55 gall which i will probably fill with a few peacock cichlids. does this sound good?

i am also looking to get 2 axolotls for my 10 gallon, would a penguin 100 biowheel (for a 20 gallon) be too strong and suck their gills off? they will be out of the cannibal stage when i get them.

That oscar is going to continues to go after anything in the tank as it gets bigger. Most likely the fin damage you are talking about is from nipping, not fin rot. If you can't go with a bigger tank I would consider downsizing the number of fish considerably. My brother had an Oscar in a 50 gallon and when it got to adult size it would chase and attack anything else in the tank, many times the disputes got heated to the point that one fish would would be chased right out of the tank and onto the floor, so watch out. In the end the only tank mate we found suitable for the 8" oscar was a 10" Common Pleco.

For many years my dad had a tiger oscar and a red bellied pacu in a 75 gal (or 100 gal, forget which). Anyways...the Pacu got HUGE!!! I am talking bigger than the oscar, and meaner too! The pacu ended up throwing his fellow large and aggressive oscar tankmate out of the tank in the middle of the night, we found him in the hallway stiff in a mid flop position. Now the pacu, nor the oscar, would ever bother his smaller catfish in the tank. Just recently he rehomed the little catfish and the pacu and re-did his tank into a saltwater tank, I havent seen it yet, but I hear it is much calmer than the freshwater one with his big meanie in it! lol

Oh, and watch out for your bumblebee, those guys can get pretty mean!!!

I dont know if I would mix peacocks with a bumblebee. Peacocks are pretty laid back as far as cichlids go, and bumblebees are kind of meaner than a lot of cichlids when they get older, of course I have heard some people say the complete opposite. I wanted to put bumblebees in my tank, but I knew with their aggression issue it would be hard to find tank mates, so I skipped it even though they are so pretty. If you buy the peacocks the same size as the bumblebee and rearrange the tank for distraction when adding the peacocks, it might be okay IMO. That way any territory the BB has claimed is partially up for grabs when rearranging for the peacocks...plus if they are the same size, they arent as easy to pick on.
Good luck...would love pictures once you get it all set up!

I've seen people bring in 20in pacus to my lfs. They are best left in the wild or a huge tank (300+ gallons). I would try rehoming the pacu and upgrading your current tank for the rest of the fish.
