I have found my fish often will not hit something they are not familiar with (on the surface). So if they are not used to eating the beetles, it might take some time to associate them as food.
Same thing with lots of animals. Back when we had cows on the place as I would check my corn fields would bring back some ears of corn in the back of the pickup. When done looking at them would throw them over the fence to my nephews cows. The ones that knew what whole corn on the cob was would eat them. The ones that didn't often would just sniff the ears and leave them alone. But after a few weeks of several batches of corn on the cob most if not all the cows would eventually get the idea and be pushing each other around to get to the corn.
Fish may be the same way. I have thrown grass hoppers into the pond in the summer and be amazed that the grass hopper swam back to safety. Not always but sometimes (tiny grass hoppers they tend to nail immediately though). But throw a hand full of pellets and you would think the BG were starving. BG prefer to eat what they are familiar with. So it may take some time and experimentation for them to eat the beetles.
