have a 20 gal waiting in the wings, still trying to decide what to stock it with. really like tiger barbs and was considering making it a tiger tank with a school or 6 or 8. but i adore cory cats and will have pandas in one tank, juliis in another and was hoping to put paleatus (peppered) in the 20 gal. will the tigers bother the paleatus (peppered) corys much or will they leave them alone? (i figured maybe because they are a bigger cory the tigers may not bug 'em much)
