What to do if your betta is Chasing discus fish?

Chasing is standard behavior found in fish, and it could cause health problems in the fish chased by other fish. There are many ways you can stop the chasing behavior and make the discus fish develop their territory.

Put the dominating fish aside

Many aquarists face the problem when new fish is introduced to the betta in the tank. In such a situation, you should find the dominating fish in the tank and quarantine the fish for a few days in a separate compartment. 

The betta would start producing stress over the discus fish from the first day and feel they are not part of this region.

It will allow the discus fish to get used to the water condition and territory. Also, the discus fish will develop their territory in the water, making them feel dominating to safeguard their region. 

After a week, bring the betta back from the quarantine facility. The betta no longer chasing the discus fish, and they stay away from them.


Use the plant to create hiding space. Betta gets aggressive when they find other fish looking at their territory, and the plant will reduce the close encounter and put both the fish away from each other.

Also, hiding space will allow the discus fish to hide behind the plant when betta chases them.

Betta generally lives in the water, where it’s fully covered with different kinds of water plants. So when they do not see a plant in the tank, they develop stress. 

The betta would think they are exposed to the preditor and will quickly get killed in the attack. The plant reduces the pressure on betta and makes them calm and relaxed.


Separate their feeding area. Do not allow the betta and discus fish to come to one place during the feeding. The food should be served at the two different places to eat comfortably without bothering each other.

Have betta eat food on one corner and discus fish on opposite corners of the tank to have their food without worrying about the other fish in the tank. 

Betta becomes aggressive when they see other fish-eating their food, and they will start chasing discus fish and push them back.

Partition in the water

The technique of adding partition in the tank could allow the fish to stay away from each other. Use a transparent sheet of acrylic or glass in the center so both the fish can see each other. 

Place the transparent sheet for a few weeks and remove them after that. Fish in the tank will develop the habit of not crossing the line and going to the other side of the area.

They will still believe that a transparent sheet between them will not allow them to go another side. 

Remember that this technique only works for the exiting fish in the tank who have seen and experienced the transparent sheet in the tank. The new fish introduced to the tank may start crossing the line and enter the other fish region.
