There are 2-3 little grey-purple starfish around and on my hornets every day. The Purple Hornets haven't been opening to full potential this past week and they seem bothered. I think the issue with them not opening might be something else, or it could be the starfish. My Red Hornet seems fine as of now, and overnight it actually shot out some new tissue that should start a colony soon. I have my hornets about 8" from the lights and 6" from the surface of the water. Can the starfish harm my hornets? Should I remove as many as I can manually?
