Was this second video take earlier than the first one you posted? In this case, the jawfish is behaving essentially normally, but in the first one, it is lethargic and breathing heavily.
That pipefish is going to be difficult to feed long term unless it has been trained over to prepared foods.
What is the full list of fish in the tank?
Do you have a treatment tank available?

We didn't have a fish hospital tank set up before, but are setting up a 20 Gallon right now and have a temp adjusting heater. (Hopefully it will be big enough cause my partner didn't think we had room to set up the 40 gallon)
I also got a submerssible UV light but waiting for some black plexi sheets to come in the mail so I can make it a protective box for the biocube.
Feeding frozen rods eggs, marine buffet, and brine twice a day with garlic guard
Fuel for the corals twice a week
Thank you for your advice, it is greatly appreciated. We definely got too excited and filled out our tank too quickly :/
