i dont think if feed roaches to my fish. bcuz i spill the food alot and spilled roaches leads to infestation
I see people coming in all the time when I'm at the LFS to buy crickets and the attendants have to count them out individually. I find this strange when there are literally hundreds of crickets and grasshoppers outside. All one has to do is turn on the porch light and set out a little dog food you get all the super fat crickets and grasshoppers you want, not scrawny like at the LFS. But I would never feed them to my fish because mostly all they do is float like a corpse when they accidentally land inside my aquarium, my fish have never eating them. If I really had no alternative I would at least liquefy them in the blender then pour them out for dehydration and make flake, but since I have no roaches (knock on wood) I would leave them out.
Blending them and dehydrating them sounds like a nasty process, I don't think I could handle that. What someone could do is start a earthworm colony. They are good to feed to fish, esp. if you like to go fishing in your creek/river/lake.
