Pineapples that hang out
The Japanese Pinecone fish can be found in the sublittoral zone of the ocean (that part where the sunlight can still reach the ocean floor) and they spend the day in caves, in coral reefs, underneath rocks, and in rocky overhangs (Weird Fish of the Week, 2016).
That is all it does during the day – hang out. This nocturnal species tends to just hang around in dark areas in the daytime before venturing out to go and hunt for food. In particular, the Japanese Pinecone fish form predatory schools closer to the bottom of the ocean floor where their diet of smaller fishes and shrimps are more concentrated.
Location-wise, the Japanese Pinecone fish can be found around the Indian and Pacific oceans, as far north as Japan to as far south as Australia and New Zealand. Other species of Pinecone fish can even be found in South Africa.
