This is because angelfish are not fast swimmers. Wondering where they came from? Angelfish are endemic to a large area of South America, including the Amazon River. In addition, they are popular for having long fins that resemble an angel’s wings.

They may be called “angels,” but they got a pretty nasty side, too! However, it is something that is in their nature. If a fish can fit another fish in its mouth, it will usually do so!

Angelfish are generally peaceful sea-dwellers.

Generally, angelfish are peaceful. They only tend to be aggressive when trying to pair off to spawn or lay eggs. They can also be aggressive when trying to establish a hierarchy among fish types in a tank.

They usually have long-term relationships and they protect one another from threats. Some breeders have experienced and noticed that upon the death or removal of one of the mated pair, some angelfish refuse to mate or to pair up with other angelfish.

Angelfish can lay from 100 to 1200 eggs.

Depending on the species, an angelfish can lay from 100 to 1,200 eggs in one laying, depending on their variety. A pair of angelfish has the capacity to produce eggs every two weeks if eggs are removed from the aquarium immediately.

Both male and female angelfish take care of their fry.

The female angelfish usually lay eggs on broadleaf plants in the aquarium or glass of the tank. It will lay a line of eggs, which the male angelfish will fertilize. The process will continue until around 100 to 1,200 eggs are laid. Both parents take care of their young throughout the development, they swim very close to the eggs to maintain a high rate of water circulation. Once the eggs are hatched, the fry stays on the surface and survive by consuming the residue of the yolk sacs.

Angelfish is susceptible to ich parasite.

Ich, also called white spot disease, is a common parasite that attaches itself to the fish. The parasite can spread, starting with one fish then onto the next. They live within the tank, before getting into the fish. Some factors like congestion, poor diet, and habitat may lead to ich infestation.

Angelfish is vulnerable to Gill Flukes.

Gill Flukes is a parasitic disease that affects the skin and gills of fish. This is usually caused by stress and improper tank conditions. The parasites may get into the skin of angelfish and may result in ulcers and infection. When infected, angelfish may experience red skin, breathing difficulties, and gills that look chewed or shredded.

Angelfish prefers water temperature between 78°F and 84°F.

Captive-bred angelfish accept different water conditions, though they prefer warmer water. It is also important to keep the water pH level between 6.8 and 7.8. Ideally, water temperature should be between 78°F and 84°F (25°C to 28.8°C).

Male angelfish has forehead bump while female doesn't have.

It is quite hard to differentiate between male and female angelfish. Male angelfish have a forehead bump or hump, while the female has none. Moreover, the ventral fin, (fin near the belly), of the female angelfish is smoother and round. while males have forked ventral fins that resemble a Y-shape.

Angelfish spend their time swimming on the top surface.

Most of the time, angelfish swim on the top surface or close to the top surface of the tank. Hence, it is ideal to choose tank mates or other fish with angelfish that hang out in the lower areas of the tank. This will keep the fish from attacking each other and will also lessen fights over food.

Fish that are at least 2 inches in size would be the best tankmates for angelfish.

Size is an important factor when choosing tank mates for your angelfish. Angelfish will eagerly consume smaller fish that will fit their mouth thus it is not good to make a 1-inch fish their tankmates. Preferably, angelfish tankmates must be at least 2 inches or 5 centimeters long. However, it is not safe to house them with big fish like jaguar, cichlids, Oscars, or redhead cichlids.

Angelfish's best tank mate can be Corydoras Catfish.

One of the most compatible tank mates of angelfish is the Corydoras Catfish. Corydoras Catfish originated in South America. They often stay in the lower part of the tank, while angelfish stay most of the time on the middle level, which means they will not interact with one another. Other fish species like Dwarf Gourami, Boesemani Rainbowfish, and Praecox Rainbowfish can also be good tank mates for angelfish.
