Well i learned an important lesson this week never put your frags on live rock till you glue them down. I lost a couple heads of a galaxia that feel on top a Torch face down, also learned to watch my water level closer i have a surface skimmer attachment and it got low, so air mixed in so water got real turbulent and ripped apart part of my torch lost one whole head. pretty sad this morn. Sad i learned a lesson at the expense of my beautiful coral.
