So, while our survivors of our house disaster were housed in the temporary trough, they were all squished and on top of one another and there were no issues. Moved them into the DT and two of them started fighting and killed each other. They were both encrusted on the rock and since they coexisted for months thought nothing of leaving them like that. Have no idea what the melted pools of acropora were that took up residency on the back wall rock during the trough days. The beautiful now deceased green acropora did not survive the battle. Both are bleached and browned out lumps . I guess all the space was too much and they had to fight to the death ??? Everything else in the tank is fine.
