Thanks everyone. While all stingrays are cool to watch she (and all Batmans) do add another layer of "interesting" to the topic. She does look rather ghostish in that second video. LOL
Keepinfish - We aren't really sure, she doesn't have the insane appetite that all the rays we have kept in the past did. Of course, she doesn't have much competition either, the others were always with other rays and it was eat now or go hungry. She eats pretty much at her leisure. She will ONLY eat frozen krill, live ghost shrimp and cut up smelt. She will turn away from EVERYTHING else. We have offered her about every form of worm and other foods out there, but she isn't interested and we aren't going to make her go hungry to try and convince her to broaden her food choices so she gets what she wants. She was a more aggressive eater when we had pups in there with her, but I guess now she just figures it isn't going anywhere so why gulp it down. We watch her and if she eagerly eats what we put in each evening we always put a little more in. She has a Synodontis Decorus that cleans up what she doesn't eat after the lights go out.
