Well had my kelberi since wed so still new to my tank. Previous owner only fed freeze dried krill he said something I wont. I use market prawns, tilapia, and massivore. Hope he learns to like one of these cause its what he is gonna get LOL. The mono ate and the azul has eyed it up where im confident next feeding he will be ready. the kelberi paid no mind to the food. This is more of a rant unless someone has some advice LOL
