Hi I got two blood red parrot chiclids the day before yesterday they are very small so I'm keeping them in a 2 feet tank but I saw that one is always staying at the top right corner near the heater and one is dominating the another they don't stop fighting I also added some hiding spots but still they are fighting what should I do I also removed green terror from their tank as I thought green terror are scaring them but still there behaviour is same pls someone tell how to fix it. As you can clearly see in the photo

Put a divider in the tank to keep them separated so the aggressor doesn't kill or stress the other to death. As soon as you can move them to a bigger tank

With many types of fish that can be aggressive (though I don't keep parrots):

One or many, never two.
