I'm wondering if there is a good but cheap food out there. I just got some senegal bichers for my 90 gallon and want to get either ropefish or an eel. I got some hikari carniverous food sticks, which my fish love, but it's expensive(like $35 for 250g). is there a good food out there that I don't have to spend a fortune on? I see some other MFKs tanks, if they fed only expensive stuff they'd go broke!
