I bought a small fighting conch for my micro-reef tank (20 gal). I do
not think this is big enough for the guy. He burrowed in immediately,
and did not reappear for a month, when he surfaced and died. I was
sad. He literally was on his back with his foot in the air. I read
somewhere each one needs about 2' x 2' of sand to get enough to eat.
Now my open-brain coral is looking sickly. Is it possible for a conch
to damage live sand?
