If these are majanos as I suspect they are does anyone know if any of the critters that work for aiptasia will work on these or do I have to go the Joes juice route? I would like to use Berghai Verrucicornis or Lysmata Wurdemanni. I have a copperband butterflyfish but he seems pretty uninterested in these guys. They may be too big for him? some of them are at least 2cm in diameter.
