Not trying to start stuff but how well do you trust the seller? IS it possible these are Leo x BD?
Maybe its just me - I do have eyes for brownies, but when it comes to blackies I'm still learning......
Whatever they "are" doesn't take away from the fact they are very nice looking, just trying to understand the differences in black rays.......
Thanks for posting the pic, love the tank. No offence meant about the Rays, I love them and wouldn't know a BD from any other so don't worry what I think.
I have only kept Marble and Pearl and know nothing about black Rays.
Do you have a lid or cover glass on the tank, it is hard to see. I am unsure what to go for on my next tank.
