Julii Cory Cat Keeps swiming in the middle of the tank

Julii is doing much better now.

My Julii seems to have slowed down a little. He is not swiming in the middle of the tank near as much as he use to. The funny thing is... if I'm standing in front of the tank. He will relax and stay on the bottom, and he seems to be relaxed. He seems to swim a lot more when he thinks no one is watching. Maybe he is just trying to get some attention.... You never know. I'll continue to keep an eye on him.... he sure does have a unique personallity!!
 
I have a school of three Julii Cats that will often go from periods of no activity to suddenly chasing the rotating output of my powerhead. I've just come to accept that the fish are crazy.
 
I've had albino cory for about a year now group of 6 but they have all started mid water swimming in the last week or so, look good while they do it just find it odd none seem distressed at all and all look healthy.
 
I have several breeds of cory's and one albino as episodes of going loopy around the tank, i find their characters funny.
