Just picked up these pups over the weekend. The male from vamptrev (larger darker one), and the female from Pat @ Amazon Stingrays. I love watching them, they like to swim up the back wall of the tank against the current of the sump return.
very nice pair, you know you got a proven male. I would just keep an eye out on the female. the male may want to poke her when she is not ready. It can get ugly.
I was wondering about that before I got them if the size difference would be a problem with the male wanting to mate early on, but was reassured it shouldn't be an issue. Either way, I will definitely be keeping an eye on both... they are too fascinating not to constantly watch
