A pound of freeze dried earth worms is about $20...why bother growing them yourself?
GASP! you shocked granny, ecoli :-/
The fish get benefits of eating fresh LIVING food.
You can't really believe that FD critters don't lose something in the process.
Would you eat only dried proteins?
Additionally, the fish engage in a just bit of natural predatory behavior- without the risk of fish feeders. My O acts all stealthy when I drop a worm in, & gets crazed when attacking & shaking them while zooming around the tank.
I always give them
after he's eaten pellets, for nutrient purposes
and so he doesn't go into pellet refusal mode.
