Thursday my Hipnopora coral sweep and touch my favorite colony a Palmata Acro. When i saw what happening i move it but are to late, the Palmata already have a bleech patch on it. Today Sunday the palmata have more than the middle bleech out. I frag it to save some frags from this spectacular specimen. This is my first incident with this Hipnopora sp., i never thouht that this coral are so agressive :twisted: . Im lucky that i always frag my corals and i have a pretty frag from this goner colony.
