Here's my video, I hope it works. He'd already been doing this "drill" for about 5-10 minutes. He would start by going to the upper left back corner, underneath the biowheel, and then he makes a downward slalom to the bottom of the heater in the back right, where there is a small leafy part of the plant back there (not seen in the video because of the ship) where he would do a backwards flip around that (sometimes a frontwards one, but usually backwards), then back up, pausing slightly to "ride" the bubbles up. Occasionally, another fish or something distracts him momentarily and he'll do something else, like snake around the heater or drift in the current, but he always has to complete the circuit before traveling back up to the back left so he can start it over again.
I had lunch with my kids and just now got back and he's resting in the plants.
I tried to take good pics, but he is just too busy for a good photo. When we bought him, he was more of a dull, brownish red, and it was all mostly the same color, and his tail, where you see the blueish tinges, it was only faint before. Now his body has brightened to an almost orange color, but his fins, the red part is a blood red, and the white is kind of variegated with the iridescent blue. You can see in the video, he has a spot on one side, I call it his tattoo. His face is darker, similar to his tail color, but close to his mouth, it's flesh colored, much lighter than his body.
We've had him 2 weeks, and he's been in this aquarium only since Saturday. I feed him Hikari pellets (not a fan, but it's all the LFS had), 3-5 by hand, twice a day. He likes being fed this way, and he knows when I'm feeding him. I have to do it that way or the white fish you see, she is a pig, she is hoarding all the food. She is the only one he bows up on, he actually halfway "schools" with the other molly or platy sometimes. They have some fry and I'm pretty sure he's ate more than one.
When I added him and the loaches, my tank restarted a mini cycle (I shouldn't have meddled with the gravel, a loach went missing so I got paranoid and went hunting for him. He's fine, but I think messing with my gravel messed with my cycle a bit). I've been doing small WC every other day to manage until it stabilizes again.
