I've been battling some what I think is temperature-induced RTN in a few of my birdsnests and milli. A baseball sized birdsnest that looked healthy on sunday was completely white and dead on monday evening, and then last night when I got home right before the lights turned off, I saw that my milli and another healthy birdsnest were seeing substantial flesh loss from the base up. This morning when looking at the tank before I left, I saw my recently added emerald crab sitting on my acro tricolor, so I ask - has anyone heard of emerald crabs harming acros/SPS? Pretty sure the emerald couldn't be the culprit of the whole colony loss seen on Monday, but maybe it's causing some of the others?
