So yesterday I bought 4 Amano Shrimp from my LFS, I bought some Algae wafers to feed them too. I have 6 corydoras in the tank with them and I was expecting them to hog the wafers so I split it in half and put them in speedster sides of the aquarium, only to find out the shrimp won't acknowledge it. I assumed they didn't know it was there, so I moved it closer to them as they hang out on a piece of Driftwood. But the still ignored it, even as the walk over it they stop eating until they get off of it. Is this going to be permanent or should I just wait a while?
