Ed,
I know the bass in my aquarium healed in a week or two, but that's under ideal conditions, I'm sure you'd still be able to see some marks in it's mouth. What's this, time number 3? There's gotta be somethin there. If possible, maybe you could clip the spine off the first dorsal spine or something, that way it won't affect her swimming in anyway at all. Bring a pair of dikes, just like a sculpin :-)
