I've used these shrimp for feeding Pseudosquilla and gonodactylids. They work fine except that they don't give smashers much opportunity to excercise their raptorial appendages. Still, they are a good component to a mixed diet.
Small size is not really that much of a problem feeding stomatopods. We feed even our large animals brine shrimp (Selco treated) and they can easily catch enough to do well. In fact, given that many of our animals are held in non-circulating, small containers, I prefer live food like red shrimp or treated brine shrimp because it does not immediately start to decompose. A few hours later we simply change the water pouring off the uneaten prey.
I would say that the limit for effectively using small shrimp or adult Artemia is 10-12 cm. The key to feeding stomatopods seems to be a mixed diet that includes some more calcified items. I don't use fish that much except for Lysiosquillids, but in general, just about any shellfish you eat will work as a COMPONENT to a balanced diet for stomatopods.
