how many phoenix worms should I feed?

[kwmc]

i pick out however many im going to feed. I put them in a cup with a few grains of raw rice. shake shake shake and all the substrait falls off then i pick the worms out with a chopstick. (the substrait looks like moist saw-dust)

Thank you very JonRich. Your method really works to remove substrate from phoenix worm. What a brilliant idea!!!! Awesome!!!
