As the title states I am looking to get my first ray. I know I want to get either a hystrix or a reticulata since they stay smaller. They will be going into a 55g growout tank until they outgrow it and will be upgraded to a 125 or possibly larger tank if I happen to come across a nice deal. Currently I am letting my tank cycle and will be running an odyssea cfs 500 of the cfs 700-uv. I was wondering which of the two species I should get and where is a good place to buy them from?
