Re: Food source for Tritonia diomedea

You might try Renilla ("Sea Pansy") which occur in inshore waters in Georgia and the Carolinas; these are in the same order as Ptilosarcus (Pennatulacea). The Tritonia may require a training period to learn to eat the new food source, though. There are other Tritonia in the SE US that eat various gorgonians, but I am afraid that collection of gorgonians in quantity may not be environmentally wise. Renilla can be collected by dredging (or hand-picking at low tide), and you might check with shrimpers on the Georgia coast, as these animals may be a by-catch component, so would otherwise be wasted. It is also possible that shrimpers collect other sea-pens which might be perfectly acceptable to Tritonia diomedia.
