Well, today I went on a trek around all the pet stores in Madison Wisconsin, and I found NOTHING yellow!!!
There were a few that were pale, but I could tell that they wouldn't color up to be the yellow that I would like to see... What a disappointment. I did, however, see some very nice HMDT?? I think they were, I will post pictures. Their fins looked as if they might give the fish trouble they were so huge.
But yes, alas, the only success in the trip was knowing where I can buy a ferret baby when I'm ready for one :)
....Just keep swimming...
