Well, this is what I found so I take it they are the same thing. (Snowflake vs Phantom):
" Black phantom and black snowflake are the same "breed" different breeder. Black ice is the step between snowflake and the black snowflake/phantom. The black ice is like the first (or couple) generation of crossing Darwin (black ocellaris) and the snowflake ocellaris morph. " -seamonkey84-
Like I said, either way they are pretty nice. Phantom just sounded cool and I thought I might have an "exotic" of some sort. lol!
