Is this normal?

Hi, my return pump broke around 5 days ago, and while I was waiting for the new one to come in, I placed a small power head into the aquariums long with the heater. That little pump was quite strong and it moved some sand around. I got the new pump 3 days ago and it’s been good but I have not seen my hi fin goby that I introduced to the tank 2 weekends ago. I’m worried because I see the shrimp often and the goby used to always be out there guarding its burrow. Is this normal or is it likely that it has died?

Hard to say....just have to keep an eye out for him. I agree with your concern though.
