I've noticed small red dots on an acro I have, my question is, do the red bugs only eat acros or other corals as well. I can post some pics but good luck on making them out since its a phone camera atm. I have had one acro lose most of his base and he is purple so I thought maybe it was the light and upgraded. The other is green and is the first time I have seen the red spots. They are not flatworms due to how they move imo. Ill post some bad pics soon
