I have a 90g FOWLR
with an assortment of Angels, Tangs & a Harlequin Tusk. I know that the Harlequin Tusk usually makes a good meal out of small crabs. I saw for myself as all the hitch hiking crabs & even a small spiny urchin was hunted down by the harlequin.
But what I wanted to know is: Can any snails be utilized for algae clean up/maintenance on the LR
How about the larger mexican Turbos? Will a Harlequin attack snails?
