Black Worm Feeding

[newmonium]

After reading some great articles on feeding lice blackworms to your reef, I decided to try. I read that feeding these will also keep the fish in reproduction health. My question is, will it also spawn new aggression? I have a Clown and a flasher wrasse. They usually swim together and are pretty buddy buddy until today (3 worm feedings later). Now the clown seems to be chasing the Flasher. Coukd this be due to the blackworms or is there something else going on?
