Red terror hiding

[Dnb23]

Hi everyone. I have been breeding a few red terror pairs and got loads of fry. I then sold the adults and raised the fry. Unfortunately the large dominant female killed the six other fry I kept with her. As she grew bigger I put her in a 4ft aquarium with jd, Texas, salvini and oscar. I recently went on holiday and on my return have found the red terror had killed all of the tank mates. She is unharmed but now hides all the time. What can I do to bring her out of hiding? It would be cruel to add more fish as she would probably kill them.

since you state that the fish is in a 4ft tank the chances are very slim that she'll let anything live in her territory. Maybe giant danios or something else fast and schooling but no other cichlids

Divide the tank and add a male to the other side. This will bring her out and help intensify her colors.
Other then taking another chance of her killing fish.
