The only time I “target” is when I feed frozen mysis. I will use a turkey baster, and with the flow turned off will make sure some ends up on the Goni. Other than that, I feed PhytoFeast Live and Oyster Feast every day. But I have an Indonesian Goni, some species from Australia are more photosynthetic and don’t need to be fed like that.Do you target feed? Anything special? What happens when they are exposed to air?
