I just received my latest order of live white shrimp from www.livebrineshrimp.com and there were 2 small pipefish mixed in with the white shrimp. I never researched thease because I didn't ever intend on keeping them. Now that I have them, what do I feed them? I DID NOT order them......they were mixed with the shrimp so don't flame me for getting something I don't know how to care for. Please help. Angie
