I too have used shrimp cuisine. This is the pellet that they eat, but don't go crazy for, so I only give them a couple of pellets about every other week just to change it up for them. I am telling you. They LOVE those Omega One micro veggie pellets. Trust me on this one.
I give em that too..I just tried to see if I could induce more red color, and I have crawfish.. So I took some advice because I don't know what I am doing.They like algae tabs too.
