I had read that sponges are toast the minute you remove them from the water......and yes I also think that is a sponge ....very nice. So what I am asking is did this get exposed to air during the rearrangement?
I was just curious and hopeful for a few colorful hitchhikers like that within my live rock.(Or must they come later?)
