The marketing department recently lost one of our two clownfish.
I say “lost” because we searched high and low for her carcass but came up empty-handed (literally).
Our remaining clownfish eventually healed from the stress and disease plaguing our tank and emerged a different fish.
The first noticeably different change is new, darker coloring around the spinous dorsal. The second, more interesting, change we’ve observed is that he’s seemed to have chosen the star polyps in our sand bed as a host.
I wonder if, in the absence of the “alpha” clown, this little guy felt he needed a host to be safe.
