All About the Anglerfish or Frogfish

In this article, we will be learning about one of the unique saltwater fish, the Anglerfish or Frogfish. There are a lot of different varieties of Anglerfish in the hobby, but this article will cover an overall what you need to know if you want to keep one of the Anglerfish in your tank.

Prices: You will spend $100 to $300 for one fish, depending upon the availability of the fish. But, for a regular, single-shaded Anglerfish, you don't need to spend over $60 for one.

Tank Size: It is recommended to keep them in a tank of at least 75-gallons as a juvenile and upgrade as they grow. 

Care Level: Moderate. Mainly because of feeding. It is one of the hardest things to get them to do, so they are a very hardy fish to keep in your aquarium if you get them to eat.

Reef Compatibility: They are excellent reef fish if they are not going to mess with your corals. However, they are very aggressive towards eating the smaller fish and inverts in the tank. So, be very careful there, but it is not a problem for corals.

Water Parameter

  • Temperature: 72-78 
  • dKH: 8-12
  • pH: 8.1-8.4
  • Salinity: 1.020-1.025

Apperance

Maximum Size: Most of the ones you see can get about 12-inches long. But there are also dwarf versions that only get about four inches, like the wart skin Angler. They are a great one that many people like to get because they stay small.

Colors: They come in a variety of colors. The most common ones are reds, oranges, blacks, yellows, and whites, and what's even more remarkable is an Angler; no matter what color they are, it can vary depending upon their surrounding. They can also change their color.

Diet

They are a carnivore. Getting them to eat can be challenging at times. In the beginning, it is best to have some live food on hand. So, if you have some feeder shrimp, some feeders to entice them to eat, they will also eat your smaller fish and inverts.

They have an echo, a modified dorsal spine on the front of their head that they will use as bait to lure their prey, and it will entice your little fish out thinking his foo, and then he'll swallow them up.

Eventually, you can train them to eat, but in the beginning, make sure you have some live food on hand.

Compatibility

You have to put this fish with larger fish that won't fit in its mouth like big Trigger, Angles, and Puffers. Usually, one Angler in the tank by itself will just do fine.

Make sure to have a nice sandy bottom with lots of live rock and caves to hide in and hunt in. As juveniles, they will be more active, and as they age, they get more accustomed to hanging out in the caves.
