Thanks guys! Catherine, I had to laugh when I saw Sparky as a name suggestion. That one is probably out of the question, as a friend has nicknamed ME Sparky! (the same friend who said he couldn't think of a name for my fish, as it's much easier to come up with new nicknames for me!) But Germ, I think you might be on to something... even Piglet or Porky might work too.... of course I'll have some explaining to do if he does turn purple as someone else mentioned!
