My BGK is now about 12-13" and he mostly eats sinking carnivore pellets. I toss some ghost shrimp in from time to time, and they seem to mostly dissipear, though I'm not sure whos eating them, and also have done small neons, but they only dissipear maybe 1 a month or so, again whos eating them can't be sure, but the neons last so long by the time they do dissipear they are competing with my jumbos in another tank for size. Any one else who's had luck with live feeders of somesort I too would be glad to hear from.
