I kept a Salt setup for about 8 years.
Things went to shit real quick when I started overnight travel. My ex could not handle the maintenance.
My fave was the harlequin tuskfish, Choerodon fasciatus, is a species of wrasse
I used to keep the dead fish. Dry them and then hang them in a fishing net in my bathroom.
I had horseshoe crabs, sea horses, starfish, puffer, angle and box fish and sand dollars hanging in that net.
I took the net down to move. After being stored for a few months the box was opened to find that a mouse had gotten
into the box, gnawed a hole into a puffer and made a nest out of everything else in the box.
I was pleased the horseshoe crab was undamaged. But alas it was not to last long.
While moving to a final destination the box it was in blew off of the truck, the top opened
and the crab got airborne in the middle of the freeway. The last I saw it was threw the rearview mirror,
crashing and burning near mile marker 167.
That was the last of my fish as pets adventures.
I may do it again but it won't be any time soon.
