Black Angelfish

Stocking a Black Angelfish in your freshwater aquarium can be a rewarding experience. The long flowing fins, and beautiful color of this Black Angel taken by Sakichin is proof of that!


Often tank bred in the U.S., the shade of this particular Freshwater Angelfish is black with lighter coloration on the fins. A fish in the Genus Pterophyllum, the species originated in South America, and belongs to the Family Cichlidae. Characteristics and living conditions for the Black Angelfish include:

  • Minimum Fish Tank Size: 30 gallons is best.
  • 75-82 degrees F, pH 5.8-7.0, KH 1-5
  • The Freshwater Black Angelfish is semi-aggressive.
  • Grows to 6" as an adult.

Because of the long fins, you'll want to avoid stocking the Black Angelfish with nipping fish, such as Tiger Barbs. The freshwater fish compatibility chart will give you a list of suitable tank mates.

Personally, I have tried keeping two angelfish in my tank, but they both died early. It may be because they were weak, or sick when I bought them. I will definitely try the fish again, as you can see by the picture of the Black Angelfish, they are an attrative fish.

Have you tried raising angelfish? Did you have good luck with them?

Kuhli Loach

The Kuhli Loach comes from flowing rivers located in such spots as Thailand, Borneo, and Sumatra. The hardy fish in this picture by Kasia thrives in the small community, or semi-aggressive fish tank.


The Kuhli Loach (pronounced "coolie" ) is a scavenger that swims and plays at the bottom of the aquarium. You'll notice in the picture of this fish that it has no scales. The Kuhli Loach prefers fine sand or smooth gravel. It spends much of it's time slithering around rocks and through the substrate in search of food. Don't be surprised to find this fish burrowing into the gravel. A member of the Cobitidae family, it's generally nocturnal, and most active at night. Other aspects of the Kuhli Loach include:

  • A peaceful, shy fish
  • pH: is best between 5.9 - 6.5 for the Kuhli Loach
  • Grows to around 3 - 4 inches
  • Prefers 78 - 86 F degree water
  • Not a schooling fish, but prefers company of others

A member of the genus Pangio, this fish is great for the beginning aquarium owner. With proper care, the Kuhli Loach can survive a number of years. Feed the Kuhli carnivorous foods. They also enjoy having freeze-dried bloodworms, and tubifex in their diet.

If you're looking for a fish that is a little different, the Kuhli Loach, and it's eel-shaped body is a fun fish to have. The freshwater fish compatibility chart can give you a good idea of tank mates for the Kuhli Loach.
