It is sneaky. I got them used to it, then I'd carpet the water with 2.2mm pellets directly above the trap. All the CNBG look up while they're eating, so they're easy targets.
What is your preferred transfer method for that number of BG now?
Hand pick out the HSB, then put the BG in some water tank, and then transport to their final destination? What type/size of tank are you using for your short transfers?
