Blackout and fish

[PhantomHalo]

So I am doing a complete blackout on my sump due to GHA taking over. However, I have a Mayori’s wrasse that escapes the main tank and wound up in there. He has been living fat, dumb, and happy off the pod population down there. My question is? Without any light will he be able to feed? Just worried about starving him out since I don’t feed down there. Thanks!

Wrasses can live a few days without food, especiall, it's healthy. I was on a 7 days vacation. Feeder didn't work with zero casualty. If you worry, feed it after three days.

Yes, it’s fat and healthy. Just very skiddish and hard to catch. Hopefully he’ll come out for food.

How long would you do the blackout on a sump? 10 days?
