Behavior in the wild

[Zoodiver]

I've had them in 145,000 and 200,000 gallon systems. Not the wild, but big enough to feel comfortable in saying they are never alone. Usually in pairs or small groups. That being said, they exhibited clear traits of conditioning. No matter what, they knew the time for food. They would gather around the spot where they were fed prior to any person being there, scent of food or external clue other than the time of day.

I would expect that level of intelligence, that's awesome confirmation though. Damn I can't wait to have a ray pond, its too bad they don't do well with bichirs

I am asking about ray behavior in the wild. Sorry if i offended anyone. But this topic is just about their behavior in the wild or big open waters.

Do rays hunt for their food in groups?

When you say pairs are you referring to male / female pairs or pairs of the same sex? Reason why I ask is I have a trio of hystrix, the male will only breed with one female and keeps trying even after she becomes pregnant. The other female is same age (5 years) and he won't touch her. Even if I divide off his favorite girl, he ignores the other and tries to get past the divider to get back to her.

How small of groups do they hang out in and are there multiples of each sex or one of one sex and multiple of other in the group?

I don't think anyone was offended, I know I wasn't. I don't think you are going to get your answer as not enough studies are done and the water is often dark where the occur (not always). I think the best and closest we can get is zoo divers experience as he has access to the largest setups, good experience and interest.

I have read this sort of thing on here many times before, I suspect it is not so much as "a pair" but probably hormonal but could be wrong. I know that in Red Bellied Pirahnas the fastest growing and largest fish get attacked and eaten by the group to help keep them all the same size and not to allow one big bully to eat the rest. I have read this in studies and have quite a bit of experience of it. I was around in the trade when the first ever recorded captive breeding happened and kept a close eye on the project.
