So I am planning on buying about 20 RCS and 10 CRS for my 7.9 gallon future shrimp tank. I was looking at some shrimp foods but only 1 pet store had food that was specifically made for shrimp. But I didn't buy it because it was a huge container which I don't think I would even use half of it before it expired. So I started looking at some algae wafers. I read the labels and all of them had copper. I did see one food that seemed suitable though. It is called Tetra Prima. It is a kind of sinking food for tropical fish. The label said that it included manganese, magnesium, zinc (and others that I don't remember) "and other additives" but it did not see any copper on the label. Do you think that this food is suitable for freshwater shrimp? If so, how many 1-2 mm pellets/ granules should I feed 20 RCS and 10 CRS and how often? Wouldn't the granulate form present feeding problems (like the dominant shrimps taking most of the food and leaving little or nothing for the rest of the shrimp)?
Thanks in Advance.
