As mentioned above, the tank is too small even for what you have now. I would get a bigger tank or rehome any fish that are over 15" asap.They are living in a 100 gallon(60x18x20) right now and they are their sizes
Temensis 20”
Azul 16”
Fogo 16”
Brokopondo 18”
Red hook silver dollar 9-10”
Pleco#1 15”
Pleco#2 13”
Pleco#3 10”

Get a bigger tank and can add a tigrinus of appropriate size for a bottom dweller.
a 100 is too small for one peacock bass
Thanks you guys, maybe I will get off of bass, and get other fish to keepI agree with the above don't add anything else until you get a larger aquarium.
