I was placing fish down in my aquarium when I noticed that the Arowana is not an Arowana at all, but rather a Damselfish:

Looks like the ID for this specific fish is pulling up the wrong model if I had to guess. The description is correct, scientific name Osteoglossum Ferreirai (Black/Blue Arowana).
Sorry for the nitpicky bug report!
