Tanqua, roar loudly over the taunts. I doubt you'd be detered by a tiny little pirhanna. Then fire an ice beam down into the tank and freeze the entire contents, pirhanna included. Take two actions if necessary. If not, then use seismic toss to pick up the block of ice and hurl it into the wall.


Roar -- Ice Beam (freeze the contents of the tank) -- Ice Beam (freeze the contents of the tank)/Seismic Toss (into the wall)
