I found Honeycomb at Petsmart, and he is NOT a common color. But, like Mr.V said, they do tend to change color. You can go to my albums to see that Honeycomb was a PURE yellow with cellophane/white-tipped fins when i got him, but now his pigmentation is turning black with a hint of blue iridsecnese. So yes, they will be hard to find, but you just have to look :D Honeycomb was ALL the way in the back of the back of the shelf. VT's, are kinda what Mr. V said, because they are so commonly bred they tend to "genetically deteriorate" over time .
