lol no ghost shrimp wont eat any other fish, unless you meant do the cories and raspbora eat ghost shrimp i really doubt the cories would but im not too sure about the raspboras, i doubt it though. And they dont just eat flake foods, add a more varied diet including flakes, shrimp pellets, algae wafers, bloodworms, catfish wafers, brine shrimp, ect ect. and yes, feeder ghost shrimp are the same as ghost shrimp.
