The Ninja Chopper might create heat when chopping up to the fine powder, it does when using it to "grind" coffee. Look into a coffee burr. You can grind pretty fine with it and it won't create heat. The Chopper type coffee grinders won't chop uniformly, which the coffee burrs will.

Honestly, if you don't have the equipment to grind to a consistent, correct size, you will be better off just buying the correct sized feed. You will need to screen the fish feed if you make it yourself after grinding it to ensure that you are getting the feed the correct size for the newly hatched fish.
