If I used what mine could eat in 3-5 minutes it would be 6-7 cubes. LOL, they're pigs!
As is I feed three cubes or the equivalent in LRS frozen. I have 14 fish including 7 wrasse(4 fairy, 1 flasher, 1 leopard, 1 halichoeres), 2 clowns, 1 Copper Band Butterfly, 1 Pyramid Butterfly, 1 Atlantic Blue tang (2.5"), 1 firefish and 1 Azure damsel (2").
