First off they should not be kept in a tank... extremely large tank, or large pond only if kept... A friend and myself tried to breed them... very difficult to keep alive... at one point we had 2 males and 1 felmale all hand feeding doing AWESOME! then all of a sudden they stopped eating after 6 months and died. no reason... i wouldnt even attempt keeping one again unless i spent a small fortune on its setup. we stopped trying after those three died... we went though about 8 of them total... longest i kept one was for 1 yr 6 months... stopped eating for no reason... (at that time i never heard of anyone keeping one for longer than 1 year). however scott michael showed me a video of a guy who had one for 2 years and still going strong, at a MASM conference last year. i would stick with yellow rays or other easier rays, more adaptable to aquarium life. just my opinion. At $50 a pop they get rather expensive... regardless they are a beautiful and awesome ray, i cant stop you from buying one, you are your own person. but i believe these are best left on the reef. Shed aquarium tried to breed them as well, and failed. last i knew they had gone though over 40 specimens, and couldnt keep any alive longer than 6 months.
i have u/w video somewhere. i'll have to find it and i will try to send a link.
