So great that they eat out of your hand. How big is your tank? I'd love one of these someday but I am worried about all of the reading I do regarding how hard they are to get to feed. You obviously are doing ok.
Their current tank is a 50gallon, they will eventually live with the bichirs, just want them to learn to eat other stuff before they can be shifted, out of the three only one eats Tilapia, the others eat only live shrimp and live earthworms.
It has been almost 4years, and they still don't eat Pellets, the big guy took. More than 3 years before he accepted Tilapia as food, else it's just live shrimp and live earthworms
