When I first saw the Angler fish, I am amazed by both their beauty and behaviors. Their color will change according to the environment, more interestingly They walks and fishing. In the photo below, you can see their fins have adapted for the walk, Stronger than other fishes.
They also fishing. They have an illicium grow on their head, it looks like a worm. The illicium will wiggle and lure other fishes close the Angler. That’s their fishing technique.
Angler fish does not need a large tank to keep, Since they are small in size and not a good swimmer. Most angler sold in local fish store will grow to 6-8 inches, so a tank of 20-30 is ok for them. But wait, don’t buy a angler yet. They are predator, will eat your fish and shrimps twice their size. On the other side, aggressive fish, such as puffers, will prey on Angler. So it is best to keep angler alone in the tank.
If the angler does not eat after you put it in your tank. Go to petsmart or other pet stores to get some live glass shrimp. Next, you can train the angler to eat frozen food.
