Hello everyone! I'm new to this community and recently cycled my tank. I've become quite fond of two damsels (Chrysiptera cyanea), both of the all-blue variety, which I believe are both females. In a nutshell, one of them attempted to harm the other, leaving the latter on the brink of death. I managed to rescue her and placed her in a breeder box, where she seems to be recovering, even eating better now. However, the other damsel is still displaying aggression towards her. I'm looking for advice on how to handle this situation. The injured damsel has been in the breeder box for 2 days, and I'm eager to reintegrate her into the tank. Unfortunately, the other one is still trying to break through the breeder's mesh and harm her. I'd like to keep both of them in the tank, which is a 20-gallon long with plenty of hiding spots. However, the injured damsel tends to stick to one corner of the tank. Should I consider using a piece of egg crate to keep them separated within the tank? Any help or suggestions would be greatly appreciated. Thank you!
