In search of live fish food near me! (Lynnwood)

I have several rescue bettas and I love, love, love feeding them a wide variety of foods.
I am in search of any of the following live options, black worms, white worms, daphnia magna, or grindal worms.
You can tell me your fee/I can gladly trade you some plants that I have like, jungle val, salvinia cucullata, or amazon frogbit.
I do not have a car, but I am able to walk at least a mile or two from Cascadion way for meetups :) McCollum park/Martha lake airport park both work well for me as meet up places!
