My tank is completely milk. I run carbon, skim and have a starphire front glass. Plus I just did a water change. Now it is very similar to what you see there.
Awesome. I hope your livestock makes it through. I had this happen to me before in the past and in my case, it was instigated by a sudden drop in SG. My ATO malfunctioned and flooded my tank with freshwater. A few moments later......mass spawning. I didn't have any problems with my livestock (without a water change or carbon) so hopefully your stuff will be fine.
I thought it was cool the way they stood on their tippy-toes.....reminded me of the robot invaders in war of the worlds.
