My brains all have there ridges around their mouths expanded more then normal and wondering why they would do that. All my sps
look fantastic with great polyp extension so I can't imagine there's is water quality issues and I have brains all over my tank at different levels/flow/light so that I would think would be out to. Normally all my brains feeding tentacles are fully extended along with my acan lords but now all the brains stopped. Can anyone shed some light on why they do this?
