Okay I have been noticing several signs that I think my rays are ready to breed. I am positive that I have a male and a female. Both of my rays are around 8 inches, the female is slightly larger. They are true hystrix rays. Okay well I have noticed them getting more aggresive. They have been attacking and killing the smaller bloodfin tetras that were in the tank and were used to cycle the tank, they have never done this before. They also have shown a loss in appetite. They have started getting darker, more vibrant nicer patterns and becoming more active. And my female does this weird thing where she lies flat on the surface of the water with her eyes sticking out of the water is this normal? Is there anything that I can do? Are they really ready to breed? Should I start cycling a tank for the pups? Thanks
