You'll have between 90 and 100 inches of fish once they're all full grown. Possibly more than that. If I were you I'd exchange the plecos for otos, loachs for dwarf corys, get rid of at least 10 mollys and exchange the 2 gourami's for dwarf gouramis. Even then you'll still be over stocked. If you want that many fish, get a bigger tank.
