They're saying that because the fish is dead it has to be tethered, otherwise this wouldn't last for more than a few seconds before the fish becomes unstable and the phenomenon stops. For a living untethered fish, some level of energy would need to be expended to keep the fish stabilized instead of the tether.

Well even without the fish moving itself it wouldn't be a perpetual motion machine because the running water would be an input to the system. Agree though that a living, untethered fish would need to expend energy to stay balanced and in the right spot.

Not really. Most people wouldn't typically have a criminal defense lawyer in their phone unless they were accused of something in the past. Invoking your right to an attorney basically just means the law enforcement officers have to stop interrogating you until you've either found a private lawyer, or been assigned a public defender.

Exciting new pivot! Glad to see y'all are doing well, and congrats on getting in to YC! -Hank (from Elab)
