Okay, I know marble betta can/will change colors, but is a fancy, fantasy, monster, multi-color and marble the same thing? I see all of these names used on Aquabid and now I am confused as to what my betta is. He was listed as a fantasy betta, so I assumed the patterns would be permanent or else he would have been listed as marble. Well I was obviously wrong, because he is turning blue and purple. My other two betta's that were also listed as fantasy have not changed (yet).
I checked Betta Splendens, but the only type listed is marble.
