sorry for the crummy cell phone pic...
on that rock i had some nuclear greens growing and purple deaths racing for real estate... and today the NG's look like this... this happened to my buddies colony that i was baby sitting in my tank too... fail...
why doesn't this happen to the PD's...? or could it be that a rotting anthias corpse was laying itself on top of the colony...???
LOL... sorry...
so yeah... how do i fix it...?
