feeding tetra FD krill as it is cheaper. Once you get them coming to the surface for food they have such poor vision they poke around at the food sometimes snatching up FD krill, hikari floating sticks, and hikari bio gold +. You just gotta be patient, it took several months for me cuz of the overactive loaches and cuz they ignored floating pellets. But the krill works cuz it smells strong! Once you got one of them eating what you want, the rest just follow. I got 4, growing like weeds, and they are so habitual, staying in same individual areas under the driftwood throughout the tank.
