He likes to rest in the shadiest part of the tank with a couple of grains of sand on his head. I interpreted this as a sign that he wanted to be able to bury, and moved a good deal of sand there during the last water change. He dove right in. Very cute!
I had tentatively named him Cletus, due to his slack jaw. Since that's not going on anymore I'm leaning toward Sriracha.
I love how he goes from looking cute and goofy to acting very predatory when I wiggle my finger in front of the glass, or drop food into the tank. Super cool fish.
