I'm trying to figure out if there are any other organisms I can add to my refugium that could be sources of live food for my display tank. Right now, the refugium has a breeding pair of
pep shrimp, several varieties of macros, and a healthy population of pods and sandbed critters. Just curious if their is anything else? Is there a saltwater equivalent of a guppy, a small hearty fish that will readily reproduce (and not completely destroy my algae and pod populations) thus creating another food source? Or is that just a silly idea?
