New Angelfish Stays In Corner

Angelfish are a stunning addition to any aquarium, known for their bright colors and unique shape. Recently, a new species of angelfish was discovered in the Pacific Ocean coral reefs. This new species has a distinct behavior of staying in one corner of the aquarium, which prompted us to investigate why it does so. Explore the behavior of a new angelfish that prefers to stay in corner of the tank.

Let’s find out the reasons why is my fish staying in one corner…

Why Angelfish Stays In Corner?

Angelfish can stay in the corner or at the bottom of the tank. It may be due to stress, illness, or pregnancy in fish. Angelfish can behave this way also because the environment you provide them with may not be favorable. You should take it as a sign to correct the changes.

Your angelfish may be targeted by another fish as their food source in the tank. If this happens, they get anxious and stressed, which is why they will find a place to hide where no other fish can notice them.

Being a new fish, another reason could be not getting adapted to the new environment. Unfortunately, the parameters may not be favorable for them to thrive.

If your angelfish is pregnant, they prefer to spend the time at the corner or near the bottom of the tank.

If your fish is ill or suffering from an infection, it may hide and stay in a corner.

To not let it happen, you should clean the tank and treat the sick fish. Make water changes more often. If they hide because of other fish, then replace their tank mates with peaceful fish.

Materials and Methods:

We conducted a controlled study by observing the new angelfish species, analyzing water quality, and examining the factors that could be influencing its behavior. We placed the fish in a 50-gallon rectangular tank equipped with a filtration system that maintains appropriate water quality and temperature. We monitored the water parameters daily to ensure the fish’s well-being.

Over four weeks, we observed the angelfish’s position in the tank, its swimming patterns, and any other behavior that we could detect. We divided the tank into four equal sections and noted the number of times the fish was seen in each section. We also monitored the water flow pattern by dropping food in the center of the tank and watching its movement under different water current intensities.

What experts observed

Our observations revealed that the new angelfish species tend to stay in one particular corner of the tank more often than in other sections. We also found that the water flow pattern was stronger in the opposite corner to where the fish typically stayed.
