Surprise in the Sump

I have 120 gallon tank, with a coast-to-coast overflow covered with eggcrate and a 40 gallon sump, divided into skimmer section, refugium and return--some live rock in each to help maintain copepod population for my 1 year old (now fat) mandarin who never has learned to eat prepared food.

A few days ago I though I saw a flash in the return section of the sump, a brief glimpse of a fish. Then nothing. The next day I checked, all my fish accounted for. The next day, I thought I saw a small head with two eyes in it, I moved to get a closer look and gone, nothing.

I figured, what the heck, and built a trap from a cut water bottle with some mysis in it. This morning I was VERY surprised. In the trap was a hi fin goby and shrimp pair I had bought over a year and a half ago. I introduced them to each other in QT for eight weeks then put them in display tank. They disappeared after 3 days, I figured eaten by small blue hermit crab. I forgot all about them until yesterday.

How they both managed to go through the overflow, skimmer section, fuge and end up in return section and find enough to eat for a year and a half is beyond me.

I guess I learned how little food fish do need to survive. There are a lot of tiny crustaceans in the fuge, maybe that's all they needed....
 
I found my YWG survive in my filter sock multiple times.. bought him for over 4 months. Saw him probably three times. Pulled him out of sock 5 times, each over a week long
 
I had a watchman goby make it to my sump. They are pretty good at jumping out o fthe water when they want to.
 
One day, I was feeding the tank when I noticed the following missing:
Filamentous wrasse
2 leopard wrasses (i have 3)
1 supermale and 1 submale flame wrasse

I checked the floor, the mesh top, sump overflow.....ever thing. I only did a glimpse into the overflow as I have eggcrate covering the top and blocking sides. No signs of them so I gave it a day or 2.

After 2 days and not seeing anything I searched again. From under the tank I shone a flashlight into the overflow and guess what. ...I found all the aforementioned fish there.

Put a filter sock at the end of the drain, removed stand pipe and then they were reintroduced into the dt. Haha
 
Back in DT I hope

Back in DT I hope

Yes I put the shrimp and Hi Fin Goby back in tank. Haven't seen them seen return to DT. I'm hoping just shy and they they haven't returned to the sump !
