Little update:
- Baby fish are 99% gone; they hatched and started swimming around the tank. A few were brave enough to cover about half the 6' tank. They were quickly devoured by the other fish.
- All aggression is back to normal / minimal
The only fish to actually get some injuries was my oscar and that was because he wouldn't back down to the green terror. All other inhabitants moved quickly out of the way. While those injuries were relatively minor, the increased stress on all the fish, the increased risk of a minor injuring becoming infected, and the fact that this could happen monthly has lead to decision to make some changes. I will be setting up another tank and splitting the pair up.
Definitely learned a few things and was very interesting to watch it unfold, but not something i want to repeat regularly.
