Answer
A 120 Gallon Tank is not big enough for all them fish.
On your Oscars they reccomend 55 gallons for each oscar.
as for the other two fish i am not famailar with these types of fish,but if they are not an aggressive fish you
do not want to put them with your oscars.They will kill them.
Hope this helps
