Hey guys so I got a question to anyone who owns a falco hawkfish, do they predate on invertabrates such as nassarius snails? The reason for this question is because I am currently servicing a guys tank and it has a medium sized falco hawkfish, and I was wanting the nassarius snails to turn over the sand. The tank is currently battling massive amounts of hair algae that's the long kind. The current live stock in the tank is the mentioned falco hawkfish, sixline wrasse, blue hippo tang, and clown fish. This tank looks to be 75 gallons, the planned stocking for future livestock would be one pincushion urchin, hermit crabs, nassarius snails, possibly emerald crab, and foxface rabbit fish.
