Would this stocking list work for a 120 gallon?

lol its not your oscar who would do any picking on its your green terror, but like i said man, i think your fine trust me, as long as you give your firemouths a cave of pvc piepe to defend you will be fine lol ive done it plenty of times with way worse fish than oscars and gt.... as for filtration, i would say 2 aquaclear 110 and a good sized canister would work plenty fine....

i personally like the mag 350 canister if thats the case

to be sure just put the firemouths in the tank first to alow them to grab there territory and start defending than after a week finish your stocking list
