Google AI says he's doing a "wobble" and apparently it's good? Is this correct?
The "Wobble" (The Wiggle)
Yes, flapping the side (pectoral) fins quickly while staying at the front glass is exactly what the "wobble" looks like! He isn't just swimming; he is interacting with you. This "dance" is a huge milestone. It means he feels healthy enough to be social and has associated you with positive things (food and safety).
