Never seen it before with my own rays, let alone got such a clear pic by accident.
Here's a vid. This was roughly 5-10 minutes after introducing the male out of the pond (sump) back into the display tank. Never would have thought it went down that fast.... lol
Nope... The pond is actually the sump for the 750. There was 2 males in the pond. Both would sit there and constantly swim in to the water coming into the pond from the tank, as if they could smell the tank full of females. Once the lil guy was introduced in the tank he went and found the big girl that just had a pup a week ago yesterday, and started tugging on her.
I've had this lil male for like 2.5 years. Has been mature since he showed up at 7 inches, but seems it took a long time before he figured out how to use them. He is the father of the litter that should be due around Labor day. That will be his first litter. Then there may be one between that one and the one he'll likely have with the big girl in the video. Turning out to be a lil man on a mission to make more mini Marbles. lol.
