Yeah they are a curious bunch. Didn't take the three circling my finger long to realise I am the pellet dispensary.
Once they sort out who is who and the plants fill in more (they have been chasing each other back and forth across the front so I need more plants there to block them), they should ease back on the fighting.
Sororities are pretty volatile at times. The big blue female in the FTS was pulled from my main sorority as she was bickering with the male and another female in there too much. Her arch nemisis is in the white net re-growing her poor tail.
