Breeding stingrays is like breeding guppys but bigger. A well balanced diet clean water and a large tank with 1 male and id go with 2 females at least. Some species take longer time then other to mature. And many people say start with an motoro because they are hardier and cheaper i say go and buy the ray you fancy. What ever you do dont buy an skinny ray or an ray thats not that active.
IMHO an bd, henlei or lets say p14 aint harder to keep then an motoro or pearl or any other brown rays. There is some species that is for more experienced keepers like schroderi or menchacai for example but at least where i live we hardly ever see anything else then the most common species of brown and black rays. I keep my mature and large rays in about 26-27c and pups i keep in almost 29c.
Get as big of a tank you can get and be prepared on huger filtrationsystems like large moving bed sumps and beadfilters. Or why not an beadfilter and some large showerfilters. For large tanks you need large filters so you should look in on pond equipment in stead of normal aquariumfiltration except for sumps.
I feed my rays 5 out of 7 days a week and change about 80% water once a week in my large tank. The smaller grow out tanks i change 40% twice a week due to heavy feeding.
Rays are very sensitive to ammonia and nitrite and produces 95% more pure ammonia then any other freshwater fish due to their osmosis regulation system. Thats why you will want a big tank with heavy filtration.
