Care and observations

The Rogue Night Hunter: As juveniles, they tirelessly pick hair algae off rocks. But as they grow large, their dietary preference shifts to meat. They will wait in the dark and ambush small sleeping fish like Blennies or Gobies, grabbing them with their sharp claws and eating them alive.
