Here is what I can recommend
ms= max size
Pond: red tailed catfish ms=4', channel catfish ms=3', sliver arrowana ms=3', pacu ms=30", iridescent shark ms=40"
250 gallon: peacock bass ms=30", datnoid ms=30"
125 gallon: Blue gourami ms=4", pink gouramis ms=6", brown knifefish ms=8"
you will have to tell me what red cichlid you have like the scientific name also what parrot fish you have. The blue lobster will be fine in the 60 gallon with a few tank mates but only if you give it lots of space to hide.
As for filtration I recommend sumps, trickle tower, or large canister as they all produce a lot of waste.
Nice fish and good luck
