Coral wars??

[christyf5]

Anyone ever experienced this??

Woke up yesterday morning, my Seriatopora callendrium and yellow capricornis which have been next to each other for weeks are both covered in a browny goo. The cap is pretty much a goner, the callendrium is half gone. I frag the callendrium and save what I can of the cap. Put the cap in some small empty spots on the rock, put the callendrium next to another coral.

This morning the rest of the callendrium is gone and its taken out a two big branches of my blue acro colony that it was next to.

I've cut off every last little bit, thrown out the callendrium and fragged well below the affected areas on the acro as well as sucked up various mung that floated away, and done a 20% water change.

What the heck is this? Normal coral warfare? Those corals were next to each other for quite awhile so this isn't an instant thing, the callendrium does grow pretty fast so maybe it grew into the cap?? But in a normal situation the callendrium versus that acro, the acro would have won (they've been neighbors before). Does that goo have some sort of superpowers?

On the flip side, the cap pieces are unaffected by this so I'm hoping this doesn't continue in the tank. Pretty damned ugly thing to wake up to, two days in a row.

Now I gotta go find a piece of that callendrium, it was a beauty
