Linnaeus loves to take food from you but then will attempt to hide before properly chewing and eating it.

For anyone who’s wondering, Linnaeus is a West African Lungfish (Protopterus annectens). These fish are ancient sarcopterygians whose closest relatives, besides the few other lungfish species, are coelacanths and tetrapods. Lungfish, being true to their name, possess a lung that is highly similar to the lung of a tetrapod which they use to draw oxygen from the air. In fact this species is an obligate air breather meaning they must draw oxygen from the air as their gills have lost the ability to extract oxygen from the water column in any significant amount. West African Lungfish can grow to 2 1/2 - 3 feet long in aquaria and are an aggressive fish best kept alone.
