Rhotano Wahoo

A razor-fanged fish known to swim in the waters of the Rhotano Sea. Unlike its sister fish found in the Sea of Ash, the Rhotano wahoo has had little choice but to prey upon poisonous fish. Over time, those that survive eventually develop mildly poisonous properties themselves. A trait that can prove fatal to the alchemist who cannot discern between these two otherwise identical siblings.
