I finished building my 430 gal aquarium for my Silver Arowana and two Achara Cats. Now i want to add my 12" BGK, and 26" TT Eel. Will this work? Will my Achara's try to eat my TT Eel? My silver Arowana is about 18" and my Achara's are about 16". I've had my TT Eel for a long time and my BGK even longer. I don't want to lose them, but i want to move them out of the 55 gal and allow them to grow to their potential.
