To unlock this hidden fish, the player must take 3 pictures of any Clownfish. You can take all 3 pictures of one species, or mix and match to your liking. If you have trouble with it, try taking 3 pictures of only the Percula Clownfish or saving all 3 images to your device.
2 Blue Clownfish are required, along with 50 Seaweed, to fuse a Juggalo Clownfish.
The Blue Clownfish counts towards the Clownfish total, helping to unlock Gobies.
No blue clownfish are known to exist, besides an April Fool's prank on an aquarium forum and a few photoshop submissions. However, an article was made in March 2018 that describes a clownfish breeder community's attempts to breed a true blue clownfish. No recent updates on the outcome of these breeding attempts are available. Therefore, the Blue Clownfish has no real life relatives to compare it to.
- A video was uploaded in late October, 2017, by Youtube user "Frostbite The Bad*** Ice Carnotaurus" that depicts a blue clownfish named "Shark," but no actual evidence has been given as to whether or not this is a real blue clownfish
