Cole - With regards to protein and bloat, I suggest that you read this.

That should answer your protein % question, and anything else that you might want to know on the subject of bloat.
And I will add this, previously posted by VRWC who has kept and raised his fair share of beani.
Then take the advice being given with regards to aggression and this species. In your 55 gallon, 1 beani will be all that will survive long term. Even in the short term you won't be able to successfully grow out several juvies, unless you divide the tank into small sections, preferably with solid colored dividers so that each fish can't see each other.
