Do you know what month? I'll look for the article.
For now I'm going to stand by my opinion that the amount feeding has nothing to do with them jumping. Sorry if it feels like I'm splitting hairs, thing is, I just don't feel that the solution for prevention of jumping is "feed them more." They dart as a means to get away when startled, in an aquarium there's nowhere to dart, so they end up breaching the surface. Although .. I guess it could be that they are at worse risk for jumping if not fed enough, because they're hungrier, but I promise even if well fed there is a strong risk for jumping. The mitigation strategy should be to make sure they can't land outside water "when" they jump (ie, a well covered tank).
