Alright here it is but its a little gross
step 1: Get as many crickets as you can( preferably from a bait store since the wild ones are hard to catch)
step 2: Put the crickets in the freezer inside a bucket (this will humainly kill them) and leave them for about five to seven minutes then take them out and let thawe.
step 3: Take some twizers or scissors and cut the hind legs of since they could get stuck in the fishes throat and then, cut the crikets head head off. ( dont worry about the smaller legs they'll get grounded in the process)
step 4: Grind or smash them into a fine looking paste.

( you should still be able to see bits and pieces of the shells)
step 5: Take a rolling pin and roll the paste flat ( scraping off what is sticking to the rolling pin) and repeat till it isn't sticking any more. (this means its get ready to dry out)
step 6: Put the paste in the sun or under a bright light to dry out. ( take a piece off and see if it breaks apart easily if so, its done)
step 7: Take it out of the sun or the bright light and let you goldfish fish try some. You might be surprized to know that crickets are chawked full of protein!, so this is a very nutritional snack to give them and is great for koi too.
step 8: Put the flakes in an air tight container or empty golfishfood can and put in fridge to keep it nice and fresh.
My fish cant get enough of it so i give it to them whenever i make it.
