Is a 380 gallon tank completely maxed with 2 RB Pacu, 1 Clown Knife, 1 PBass and an Arowana? or cud i add more
Overall answer to question...
Completely maxed, overstocked, nothing else...
Get rid of some before trouble starts.

Just my opinions/$0.02...
Overstocked, specifically just not enough room... With just the two fullgrown adult RB Pacu.
Pacus just don't belong in general aquaria of any form, they need to school, they need mega room for swimming... Just not right.
Need a pond/lake, enclosed section of river or a multi thousand gallon tank.
PBass & Aro might work if, IF, if aggression doesn't come into play... Yeah right.
Same goes for PBass and CK.
Fullgrown adult Pbass by itself would be awesome, perhaps with a large Cat/Plec.
Aro & CK should work, can add some different tankmates.
