A four lbs bag of tilapia last two months and 2.2 lbs hikari gold plus last 3 months so it's about $15 a month for 250g of tanks.
i tried to save money feeding kens fish food products. I think they are rebranded Best Flakes foods. They are good food as fillers but if you want show quality colors then hikari bio gold plus is the way to go. Also some of my picky eaters won't take Ken cuz the pellets are really hard. On top of that hikari is engineer to reduce fish waste.I do the same. Has anyone tried ken's fish food in the bulk ? I'm starting to think I can save by getting that every month as a staple. My fish are pretty picky though... so I'm unsure if they will like it or not.
