is one piece episode 544 filler?

Arlong is enraged over Tiger's death and, rather than choosing to obey Tiger's last wish, he does the exact opposite of what Tiger wanted: as he returns to Koala's home island, he plans to get revenge on the humans that sold him out. However, Vice-admiral Borsalino is there and easily defeats Arlong.

Arlong states he's here to kill all the humans that sold Tiger out and how Tiger is now dead while Borsalino just states now he's gonna take him with him.
