Arowana Help!

[BluebellLight]

What sized shadow does the Arowana have? I've heard from some places it is large, but others say it is small like the Black Bass! Besides the Giant Snakehead, it is the only other fish I need for this month, and I'm going crazy looking for it! Can anyone who has caught this fish help me and tell me what sized shadow this fish has? If possible can you please compare it to the size of another fish's shadow too? Any help is greatly appreciated

I've caught a lot of them. Most of the time they've been the size of the black bass which are large. A few times I caught one that looked bigger.
It's best to catch fish and walk the full length of your river. Go up/down and catching fished helped me get all the rare fish.

I completed 17 fishing collection using this guide.

Found when it rained it was easier to catch the rare fish. Also found if the player fortune was good fortune on items she caught all the rare items. Just need the clothing or the special hat.
