Angels in the tank

Assuming you own just one tank like most of us poor souls, with so many different variations of fish you could possibly stock, you must be wondering which fish to buy. Tongue in cheek, here’s one choice to complete your balding pate. From the title above, you can pretty much guess which fish type I am going to write about. Yes, you are right, it’s the lovable angelfish.


The family Pomacanthidae, more commonly known by its household name “angelfish”, has vibrant colours and is very active and alert to its surroundings. A total of 75 species make up the family of angelfish. Popular types with most aquarists include the Flame Angelfish, Queen Angelfish, Marble Angelfish, Altum Angelfish and Coral Beauty Angelfish, to name a few. Though angelfish are fairly hardy in nature, they are usually not recommended for inexperienced aquarists who do not have enough experience keeping aquarium fish, because of the dedicated care and constant attention they crave.

Setting up tank

If reared in a healthy environment, most angelfish species can live well over a decade and grow up to at least four inches in length. Angelfish survive best in a tank of at least 30 gallons with excellent quality water at room temperature, with pH ranging from 5.8 to 7.2. If you love your angelfish, make conscientious efforts to scrub your tank and change the water regularly as they are generally intolerant of suboptimal water conditions.

Despite their love for active swimming, angelfish habitually seek out rocks or corals in the tank to swim around and to hide at night to feel secure. Without these structures, they might even languish and die. Thus, you should try to place as many such structures in your tank as you can, complete with ample algae growth for your angelfish to graze on.


In addition to feeding them sponge-and coral-based food, try offering your angelfish a wide variety of live and dried food, including shrimp, squid, clams, Spirulina, marine algae, and other high-quality meaty fare. Feed them no more than two or three times each day.

Harmonious living

A large tank does not necessarily guarantee harmony amongst your aquatic pets. This is especially true with angelfish, which happen to be extremely territorial and are largely intolerant of other fish, even of the same species. Fights in the tank will almost always occur between angelfish and other fish, or with other angelfish. Therefore, once you have one angelfish, any other fish you add must be of a size and personality that won’t let them be easily bullied by the angelfish.
