Angelfish are some of the prettiest aquarium fish available. Their natural habitat is in South America and they prefer quiet, slow-moving water with plenty of vegetation. Because of this, angelfish need a larger aquarium than you may think. They can grow up to six inches long, but they have long fins. Full-grown angelfish do better in a larger tank that is tall instead of wide. And if you plan on having a pair of angelfish, you’ll want at least a 30- or 40-gallon tank.
How Many Angelfish Should Be Kept Together?
Ideally, you should not have more than a pair of angelfish in one tank. Angelfish are not usually aggressive, but they can be territorial. Even two angelfish may not live together comfortably if they don’t have enough room.
How Do You Stop Angelfish Aggression?
Angelfish are territorial, so an effective way to keep them from acting territorial is to only keep one or two in a large tank. If you find you do have a pair that doesn’t get along, you should separate them. The aggression will only get worse as they get larger.
Are Angelfish Good Community Fish?
Although angelfish tend to be territorial, they are considered a community fish, so the key is to find compatible fish. Don’t choose fish that are less than two inches long, but also, don’t pick fish that will get bigger than the angelfish. And look for fish that aren’t territorial. Angelfish hang out in the upper tank, so choose fish that spend their time on the bottom of the tank.
Which Fish Can Live with Angelfish?
When looking for tankmates for angelfish, think about fish that have similar water parameters. You want to avoid other cichlids, which can be aggressive, too. Angelfish may see crustaceans and non-fish companions as prey. When stocking a community tank, remember that the rule of thumb is one inch of fish per gallon of water. Choose from some of the following species that live well with angelfish:
- Bristlenose Plecos – bottom feeders native to the Amazon River region. These fish are easy to care for and peaceful.
- Corydora catfish – low maintenance fish that are peaceful and calm.
- Platies – colorful fish that are easy to care for and amenable to angelfish.
- Rainbow fish – peaceful fish that are easy to care for and are well-suited for an angelfish tank.
Angelfish are good companions when they have suitable tank mates and environment. You’ll need to watch your tank when you put fish together, because there are always exceptions to the rule. With a little research, you’ll find the right fish to put in your aquarium.
