| help, acropora trouble
tissue gone from 2 spots on back side, seemingly overnight, they were small on sunday, bigger today. also a bit on onr side of the base
1. magnesium has been a bit out of whack, too little, too much
2. it fell over into the anemone last week, could have been there all day
3. Six line wrasse
4. hermits
any ideas what may be the cause most likely?
What to do now?
