Nah this doesnt look like distressed fish. They are probably sleeping. Our goldfish would always sleep in the same spots, and float next to each other line up kinda like this, usually in the corner of the tank. We also had a blind dojo loach who would decide to get a case of the zoomies and ram right into them and bowl them over like a reverse bowling alley.

Goldfish are super social. This looks like nap time to me.
