All I will say is TFD is hit or miss with there rays. One order you get a nice specimen and the next it is in horrible shape. Most all there rays come in with fish lice. So for you, if you know nothing about rays I would suggest not buying them through TFD. If you are die hard on getting a retic then get one from a lfs where you can physically see it eating or from a reputable vendor. They will cost more but you will have a better chance of it surviving.
