I must be overfeeding mine. I have it in with a gabillion (ok maybe slightly less) black bar endlers and mine can barely be bothered to get up off whatever plant he's relaxing on. LOL- That's not entirely true, but "voracious" is not how I'd describe him. Maybe if he was in his own tank and I put flightless fruit flies or something in there. Maybe I'll put some in- I keep them around for my hatchet fish and half the other fish I have go after them too- never tried them on the endlers because it's more than one bite for them, but maybe it's time to try.
