What do they eat and where do I get them?
They're also referred to as glass shrimp, ghost shrimp, or feeder shrimp. They are like most CUC shrimp which eat anything that falls to the bottom and occasionally I add additional Hikari Shrimp Cuisine for a treat and to make sure that they are getting a well rounded diet. They are available as feeders in many LFSs and can be purchased online. They usually cost about $1 for a dozen (or comparable) so if you were to ask for just one they may even give it to you (especially if it is a store that you frequent and you tell them that you are working on an experiment). Personally, I use them as part of the CUC and not as feeders. The ones that I have I collected on the coast.
