what is thier max size round?
This can vary a great deal.
My largest female measured 15" across the disc and my largest male was 10" disc.
12-14" is the norm for most females and anywhere from 9-12" for a male.
It is possible for a pair to breed before reaching the above sizes providing they are old enough and the male has large well rolled claspers.
Hope this helps.

I was just reading up on these today. I'm picking up a 60"Lx18"Wx25"T tank for my smaller arowana to grow in, and I was thinking about potential tank mates. I've never owned a stingray, and the hystrix seemed like a decent beginner ray.
If they max out around 12-15", then one should be ok for a year or so in my new tank, right?
