I have never kept a ray but I have done tons of research ever since I started building my 360 gallon tank. I am just wondering what species you guys would suggest if I was looking for a species that will stay in a 3' wide tank and eventually breed them. I have read breeding isn't rare or too difficult in aquaria. I work at a LFS that is kinda low on oddball fish so I am looking to breed primarily for my own enjoyment but also try to take some to the store to help inform and sell some pups if I am successful. I was thinking Hystrix but am open to other options!
