This man didn’t clean his fish tank for more than two years, and after he decided to finally pay some attention to it, he noticed some strange movement between the stones on the bottom of the tank.
When the man got closer, he revealed a meter-long bobbit worm, which lived there for all these years!
That’s a killer worm which eats corals and small fish, but looks like it wouldn’t mind to taste human flesh as well.
“It hides in the rocks, and only comes out at night, impossible to catch without taking everything out the tank,” the uploader wrote.
It measured 1.2m long. These worms can grow to sizes of nearly 3 m (10 ft) in some cases.
