I suggest you visit pet-pourri in everett, they have an awesome selection of fish and a decent selection of plants. That would be the closest one to you that is a decent shop. There's also jones pets in marysville, but they pale in comparison.
Also, they have live blackworms, which I can vouch for... If you have fish you want to breed, get 2 portions of black worms, and feed it to your fish for a week, you'll have breeding in no time... They're like viagra.
