unfortunate update. he didn't make it. hemorrhaging was too great. When I had pulled him out of the tank to put him in quarantine the entire top of his body was dark brown (blood red + cichla green). Still not sure what caused it. But I'll be looking in to the tank today to see if something is up.
interestingly, the female is showing signs of loneliness, but she is showing her regular normal behavior again. begging for food, hitting anything that drops in the water, normal swimming, etc. This makes me think her empathy was not from a relationship type bond but more from a same species bond. She saw one of her own kind in distress and tried to help, but once the distressed animal was removed, everything was normal again.
