Did a big re arrange of the tank I redid all the rock work and tosses stn stuff and changed a majority of the water. I had a rock full of those neon green zoas I had no where for this rock so I tosses it in a bucket and siphoned the tank into that bucket. I forgot to dump the bucket and 2 weeks later they are still alive and still green they are somewhat extended. A bucket with old tank water and no nothing. It almost makes me question some things we do to our tanks if these things are still kicking.
