How many Angelfish in a 25-gallon tank?
A 25-gallon tank can fit a maximum of 2 fully grown Angelfish. Angelfish need to swim, explore and establish their territory in a fish tank and a 25-gallon tank makes this doable. It is also possible to form a small community in a 25-gallon tank.
What you should know about Angelfish
Angelfish are very popular triangular-shaped freshwater fish. They are classified as semi-aggressive because, in some conditions, they may become aggressive or territorial. However, most of the time, these fish are peaceful.
They require low effort to keep them. Which make them good choices for beginners and community tanks. On average, they measure up to 6 inches in length and 10 inches in height. In captivity, Angelfish live for around 12 years.
The recommendation is to feed them twice a day. As omnivores, this should be done by offering them some fresh vegetables, live bloodworms and brine shrimp, freeze-dried items, and some industrialized flakes and pellets.
What are the best tank mates for Angelfish?
Although they are semi-aggressive fish, in general, they remain pacific. Thus, they can be kept in community tanks with many tank mates.
Tankmates should not be aggressive or become fin-nippers at some point. Also, it is important to highlight they cannot be small enough to be eaten by the Angelfish or big enough to attack them.
Here, we have some of the Angelfish best tank mates:
Bristlenose Pleco – 10/10
Bristlenose plecos are natural to the same region as the Angelfish, the Amazon River basin. However, they are bottom-dwellers. This means they feed mostly on material sunk or growing in the bottom of the tank. They are very peaceful fish species that can do well with many others. Additionally, they are not demanding fish that enjoy planted tanks.
They also feed on the growing algae, which will help you with water quality control. Water temperatures should be between 70 and 77 degrees Fahrenheit and they can grow up to 6 inches.
Corydoras catfish – 10/10
Corydoras catfish or only corys are a group of several species. They are, in general, great inhabitants of community tanks. And similarly to the plecos, they occupy the bottom layer of the tank.
Corys are also very peaceful bottom-dweller with a very relaxed temper. Also easy to maintain and should be placed in small groups of 3 or 4. Their water temperature requirement is around 72-78 degrees Fahrenheit. And they can grow up to 2.5 inches.

They are hardy fish also and breed very easily. They grow up to 3 inches and their temperature requirements range from 70 to 82 degrees Fahrenheit.
Platy fish – 10/10
Platies are highly recommended fish for novice hobbyists. They are hardy fish and have a very relaxed temper. They look amazing in bright colours. They also breed very quickly, thus be careful to avoid overpopulation. Their water temperature requirements range between 68 and 79 degrees Fahrenheit and they grow up to 2.5 inches.
Angelfish tank tips
Angelfish natural habitats are the calm placid waters from the Amazon River basin. Warmer temperatures and great vegetation is a must in Angelfish tanks.
Water parameter is the most important tank characteristic. Controlling them will guarantee lower contaminant levels and thus, lower vulnerability to diseases and stress.
Some equipment may assist you in controlling and stabilizing some of these parameters, such as filters and heaters. Temperatures should be stable and a bit warm, ranging from 78 to 84 degrees Fahrenheit and pH levels between 6 and 8.
Due to the Angelfish temperament and size, it is required around 16 to 20-gallon per fish for a tank. They require plenty of room to have plants and substrate in place, as well as to swim around and explore.
Although Angelfish are not schooling fish, they appreciate being in small groups rather than being left alone, once they feel more secure in the companion of equals. A 25-gallon tank can house 2 fully grown Angelfish.
Plants and Substrate
One important point when setting up a fish tank is their natural habitat. The more natural the tank look, the happier the fish. Thus, having some live plants such as Java moss, Java fern, Acharis, or Amazon sword will make the tank look similar to their natural environment.
Substrate should be fine sandy as they enjoy picking the leftover on the bottom. They also appreciate plenty of hiding spots.
