i have a 55 gal planted tank with a doz crs and 6 orange bee shrimp. I just ordered some cacatuoides, are they gonna eat my shrimp? If the cacatuoides are small enough and the crs breed can they live in harmony. Are there any "cleaner" fish that will leave the fry alone. I have a sae, flying fox, a bushynose and a blue phantom pleco, and a few otto cats. If the cacatuoides have plenty of caves and places to hide will this enable them to breed and multiply?
