Thanks for the feedback.
His claspers are nowhere near as large in proportion to the his body like in the pics above.
I have not seen him bite her.
There are 4 large bichirs (1 endli, 3 ornates) in the tank as well as 2 8-9" niger cats and 2 10" giraffe cats in terms of bottom dwellers.
There are 4 dats who haven't shown any interest in the rays.
2 pbass between 10-12". They have shown no interest in the rays.
1 RTG who hasn't shown any interest or concern over the rays.
If I were to suspect one fish, it would be the largest ornate. He's a grumpy sob, but onyl towards the other ornates.
Why do I think it is the male ray? Because he has remained unscathed since being placed in the tank. If it were another occupant, I would think the male would have been bitten already as well.
He is well fed. The female eats a quarter of what the male eats.
She has no new bites today.
One thing I did notice when watching them last night is how one of the giraffe cats was using both rays as a scratch pad for about 20 minutes. The f****r was targeting the rays specifically, so the cats are going to be moved in to a different tank. I already knew that giraffe cats can be annoying towards rays and I now know how.
