What do you feed juvenile Geophagus Altifrons? I imagine a good sinking Cichlid pellet would be important. What brands to you recommend? Also, would I need to supplement with a spirulina type food product? Do you feed any frozen foods ( such as Hikari brands) in addition? I will also have on Threadfin Acara in tank, will it eat the same diet, or need a more specialized food?
