So I need to buy some new fish food bc the hikarI staple minI floating pellets are too small for the cichlids I have. I have a severum, blood parrot, kirin parrot, and jack dempsey. They are all over 4in. The largest is the severum at 6in (measured from head to the beginning of the tail). It needs to be pretty cheap and preferably from walmart but petco is ok too.
