Ahhhh I’m seriously craving some pineapple after looking at dozens of Pinapplefish (Cleidopus gloriamaris) photos!! Also known as the knightfish or the coat-of-mail fish because of the armor-like scales that cover its body, the Pineapplefish might have many great qualities however swimming isn’t one of them. That rigid armor paired with tiny fins make it more of a floater than a swimmer. For that reason, you can find these fish under rocky ledges or in caves during the day. 
Oddly enough, a small group of Pineapplefish have been documented hanging out in Fly Point Halifax Park Aquatic Preserve, New South Wales under the same ledge for at least 7 years, and another group under a different ledge for 3 years. So, if you ever want to find a Pineapplefish, at least you know where to look!
