Anyone else have fish that do "odd" things?

My regal tang fits right in with Dory from Finding Nemo. In fact I think her name was Nori when I first got her, we mostly call her dipshit now. Every day after eating, she races to the surface of the water takes a gulp of air and then streaks back to the bottom of the tank, letting the water "fart" out her gills. She does this repeatedly for about 10 minutes.

Today I discovered she's busy at the surface of the water at one end of the tank. She just angles herself parallel with the waters surface and flips her fins and tail to splash the water (up onto my lighting hood of course which is now completely soaking into the wood ). After doing that for a few seconds she streaks away only to come back after about 15-30 seconds.





Currently she is doing the same flippy type thing but in my staghorn coral which is next to the glass on the right hand side of the tank. Often people think she's stuck in there but nope she's just being an idiot. I can actually hear her hitting the glass with her side. She kind of reminds me of a clownfish fanning her eggs.

I often wonder if this is the result of being in captivity for too long or these fish are really that "special"?

Anyone else have any odd fish?
