Lethe has indigo hair. 

And yes. Felicia is the fish one. ;) She is flighty, scares easy and enjoys the water more than the land (although she hasn't spent much time swimming lately). Like the creatures she makes a living off of, she is satisfied living her simple life and goes with the flow. Her curious side is always coming into conflict with her overly-cautious side. In that way she is like a smart fish that has already been caught once and is determined not to get caught again.

Hey Heilix-- give me a chance to change Frore real quick before you post. I'll change him after Ops and Geico post. (I just think it'll be more entertaining for him not to know Frore is a Chilfos yet.)
