At first they appeared to be pairing up. They were dancing and staying side by side, cleaning surfaces, etc. Now they just face off all day, twitching violently. They look great. Fins intact, eating a little less but not starving. The water is in great shape, too. I'm mostly wondering if the stress will eventually start doing them in or if they can continue on like this indefinitely. Their mouths get a little raw from time to time if they get into a liplock battle, but it always heals up in a day or so. Should I move one to another tank or maybe split the tank up into more territories? I recently rescaped the tank and did more caves/slate while removing most of the ungodly plastic plants. Perhaps this triggered the aggression? I want these angels to live a long, healthy life and realize this question seems a little off. By no means would I ever be okay with inappropriate living conditions for my fish, but I'm not clear on how to manage this situation.
