Why Is My Angelfish Swimming At The Bottom Of The Tank?

Angelfish, like other aquarium fish, have their typical behaviors. These behaviors, alongside other physical features, usually account for the differences between the species. However, some actions are not rational; they can mean something is wrong in your tank.

Why Is My Angelfish Swimming At The Bottom Of The Tank

If you find your Angelfish swimming at the bottom of the tank, it might mean something is wrong. It can be a result of poor water quality. It can also be due to improper water parameters such as pH, temperature, and ammonia levels.

Unlike some other aquarium fish, Angelfish are not bottom dwellers. It is not healthy to spend a lot of time swimming at the base of the tank. Instead, they spend most of their time in the middle or toward the fish tank’s surface.

If you ever find this happening, you have to pay special attention to your tank’s condition. It might even be mandatory for you to take rapid steps. But first off, you might need to understand the general behaviors of Angelfish.

General Behaviors of Angelfish

Angelfish is a brilliant choice for aquarists. They have attractive behaviors that add life to the tank. They can also add color and beauty to your aquarium.

Angelfish have a wide range of characteristic behaviors. These behaviors range from feeding habits, aggressiveness, to swim patterns. Aquarists need to understand these patterns of behavior.

First off, it is essential to realize that Angelfish are active swimmers. They often swim in the middle of the tank rather than the bottom tanks. You can also find them playing around the surface of the tank on a few occasions.

Also, Angelfish belongs to the cichlid’s family. Therefore, you can expect a trace of aggressiveness, particularly towards other members of the family. However, Angelfish are relatively peaceful when compared to other members of the family.

Another notable behavior of Angelfish is that they are timid. Angelfish often get scared by the slightest disturbance in their environment. They get scared by any sudden noise or movement within and outside their tank.

Angelfish also have the typical behavior of pairing up. They often pair up during breeding to form a stable couple. Aside from these pairs being parental partners, they also team up to defend their territory from intruders.

Moreover, Angelfish are opportunistic feeders. They are omnivores; thus, they will eat both plants and animals. They will eat almost anything that can fit into their mouth, notably smaller sea creatures.

Also, Angelfish do not damage or disturb the live plants in their tank. They neither eat them nor feel uncomfortable with them. Instead, they take them as hiding and resting places, as well as a simulation of their natural environment.

Angelfish are also egg layers. They often exhibit some creative behaviors during their breeding season.

What Happens When My Angelfish Is Swimming at the Bottom of the Tank?

Angelfish are active swimmers. They often love to swim in the middle of the tank. If you find them taking too much time to swim at the base of the tank, it might mean something is wrong.

One of the things Angelfish detest the most is poor water quality. Once you find your Angelfish swimming at the bottom of the tank, you might have to check the water quality in the tank. You might have to evaluate the level of ammonia and other toxins.

Another reason that might account for the swimming of your Angelfish at the bottom of the tank is weak water parameters. These parameters include pH levels, water temperature, water hardness, and salinity.

Angelfish can give an adverse reaction if any of these parameters are not in place; also, external and internal disturbance can scare your Angelfish. Consequently, they force them to seek a hiding place at the base of the tank.

Importantly, your Angelfish swimming at the base of the tank can signify the presence of disease in your tank. Specific fish diseases such as swim bladder disorder will alter the swim pattern of fish. It can cause them to lose control of their buoyancy.

Consequently, a disease like this might force your fish to swim down at the bottom of the tank. Other similar conditions that affect buoyancy in fish can also have similar impacts.

Therefore, if you notice any abnormality in the swim pattern of your Angelfish, it is best to pay attention. Pay attention to the water and tank quality. Likewise, you should take urgent steps if there is a need for it.
