I had one hitchhiker colony that did ok for at least a year... it was located right by the food output, and, closest to the light. I don't know if some of them might possibly be partially photosynthetic? But this colony did ok. Always expanded and showed a small amount of growth.
For foods Fauna Marin is the way to go. I still have the whole set of FM azoox foods I'm planning to put up for sale soon.
