Stocking help (40B or 55)

[AR115]

I have a 40B and a 55 up running and cycled and need to figure out which tank for stocking

looking to add some EB Acaras, Geo redhead tapajos, geo threadfins?, not really sure what else I can add, would love a severum or 2 but assuming they’ll be too big? All would be added as juveniles
TIA

Any of those species would need the 40 or 55 to themselves in a pair or small group. Maybe a pair of EBA in 40g. Small group of redhead geos in 55. Maybe could do a pair of threadfin in a 55, but they get a little big and aggressive in my experience for a 12" wide tank. Severums I wouldn't put in either tank long-term.

Guess i should have added that i have 2 75s as well, 1 with 3 blood parrots and the other just finished cycling and doesnt have anything but some danios in it for now so the thought would be to use the smaller tanks as grow outs, just not sure if I could put all of them in the same grow out tank...assuming no
