The goby looked very healthy and was eating the day before as usual.

I looked for it last night and this morning. The way I have my 45 gal setup
there really isn't many places to hide.

The nitrates were at 20 ppm this morning. I was thinking if it's dead
somewhere it might be making my nitrates higher than usual.

I have that large hairy crab in there. Hopefully the crab ate it but the
goby was pretty big for a goby.
