OMG, I Found a Fish in my tank I have not seen in over a Year!!

In my reef I have a yellow coris wrasse that goes missing from time to time now he is missing for almost 6 weeks. Mostly gobies and basslets appear to go missing often.
In my freshwater tank there are many catfish that can disapear for months. My current freshwater setup has a spotted raphael catfish that I saw yesterday for the first time in 2 months ish.

Well, y'all have given me hope that my little diamond goby may still be alive and well somewhere. Haven't seen him since the first night I put him in DT after his month in QT. That was a week and a half ago.

I do have a tight-fitting lid and I did do a search behind the tank, but no Moby the Goby.

I have a canister filter, no sump. Haven't looked in there yet. Not even sure they can get into a canister filter.

I hope he's just somewhere in my rockwork or sand and will come out soon. Kinda worries me, tho, not seeing him at mealtime. He never missed a meal in QT.
