Normal Behavior?

[Hancat]

Sorry for the noob question, this is my first pair of clowns.

Cycled tank with pre-seeded media/live rock for 6 weeks

8.2 PH
0 NH3/Nh4
0 NO2
20ppm NO3
0.3 Phosphate,
470 Calcium
11127 Magnesium
150 KH

I've read that they're similar to pufferfish in which they glass surf quite a bit when newly introduced to the tank, but does this swimming look...erratic?

Just want to make sure I'm providing the best home possible for Michael & Jan, thanks in advance!

Sorry for the shaky video, I have ADHD lol.

Looks pretty normal to me. :)
