Red stingrays at the Lotte World Aquarium.
Has anyone had any experience caring for the Red stingray (Hemitrygon akajei)? All I have heard about their specific requirements is that they prefer temperatures between 15 °C and 25 °C (though I would imagine their care is similar to that of the Southern stingray (Hypanus americanus)). They seem to be somewhat popular with Japanese and Korean hobbyists as juveniles, despite growing a meter across.

There are more that I cannot find. I will post later.
