Here’s one you may have never heard of before and most likely never saw in real life. And even if you did you might not have known it. It swims like a fish and acts like a fish under water, but you’d mistake it for something that was once on a tree high in the sky. It’s called a leaf fish, and it’s one of the most peculiar-looking fish around.
Curious? Here are a few facts about the wondrous leaf fish.

Leaf fish, or leaffish, have the ability to camouflage themselves into their environment.
- A leaf fish’s body is oval-shaped and flat. The fish literally looks like a dead leaf, and it tends to float around the bottom of a fish tank.
- In the wild, it can be found in the Amazon River basin.
- A full-grown leaf fish is typically about 3 to 6 inches long.
- The pH level should be 6.0 to 6.5.
- The water temperature of the fish tank should be 77 to 82 degrees.
- Its fins are transparent, further contributing to its leaf-like appearance.
- It’s an aggressive fish with a large mouth that has a pointy lower jaw – one that no doubt strikes fear among its prey. In fact, the shape of its mouth creates a suction that allows it to devour its prey quickly. Hobbyists consider this quite a sight to see.
- They are usually orange, yellow, or brown, like the color of fallen maple leaves in the autumn.
- Because it is aggressive and has an appetite twice its size, this fish will eat anything in its way. If you choose to have one for a pet, it should have its own tank of at least 25 gallons.
- Ironically, it gets scared easily, so the tank should have plenty of hiding places for it.
- It is also referred to as a leaf scorpionfish or a paper fish. There are several species of this fish, including African leaf fish and Amazon leaf fish.
- Poison glands are attached to the dorsal and pelvic spines.
- In a tank, it should be given live foods such as shrimp.
- As if its appearance isn’t deceptive enough, it also changes color to match its surroundings.
- These fish can live for more than 10 years.
