55 gallon stocking

[Lawton C]

Kinda in a pickle here...I have a 40 breeder that houses a single firemouth. This fish is very aggressive to any smaller tankmates I have tried to put with him. I have recently moved and have an empty 75 gallon. I want to use the 40B for other fish and was wondering if a bigger tank and bigger tank mates would make the FM not so aggressive.

Planned stocking
blue acara
FM (maybe)
2 red spot sevrums
10 gold barbs
1 Rio negro pleco

Thanks...Kinda new here

The best thing to keep with your firemouth is more firemouths, no less than 6.
Firemouths live in groups in nature.
I would add any new fish to the 75first and then your existing firemouth last.
