(I think) I've read in these forums that the normal feeding guidelines for giganteas is a pencil-eraser size a couple times a week. I am trying to grow my gigantea as big as feasible for my 300g. My 18" purple (5mos old) has a 1-1.5" mouth. Does anyone have the background or history behind the eraser sized feeding recommendations? If not that, what protocol are other people feeding their giganteas?
