So I have an RTC, RTCxTSN, and Marble Acara in an 180gal tank, they get fed Hakarie Cichlid Gold, sinking alage wafers, worms, crickets, beef hearts, shrimp, scalops, tilapia filets, anything seafood counter has on sale. My Quetion is, is the cichlid gold really something i need to keep buying at 12.oo a bag or something like that. They eat a little of the Cichlid Gold every two days as a filler and then i give them a few shrimp or what evers on the menu. I fill like i change it up a lot and they get a lot of good nutrients. Is there something a little less cheaper that I can buy to use as a main filler staple?
