I'm afraid to break it down by week. I just got in a regular frozen food order that runs $165. I spend about $75 a month on live foods. Dry foods come in 50 lb lots for the most part. I just refilled my 55gal bins with about 350lbs of dry crumbles, pellets and sticks. Flake foods are ordered in mixed lots of 30 to 50lbs at a shot. I also hit the local food stores for shrimp and fresh produce/meats for around $50/month. I also fish and keep 'trash' fish like buffalo, sunnies, and shad to feed out my larger preds and matamatas.
