Yes, did you read the color was discovered by a man in prison...
And they can change to solid color... had a friend that had a marble that did quite well at a show.. and within a month it had changed to solid color. Also, breed marble to solid and you will get solids, marbles, and multis... Most people don't like to work with them because of this trait...
Walt Marus is given credit by Dr. Lucas for beginning his line of opaques.. but unfortunately it carried an eye problem that still exists today.
REALLY?! thats kinda why i WANT to breed them. i see nothing wrong with being able to tell 1 fry from another (thats why i am prefectly happy breeding petstore bettas)
do all opaques have eye problems (my female SEEMS fine, but she IS petco so the she isnt pure opaque)?
anyway back to marbles:
if you need to buy a marble for breeding i saw one on aquabid, its labeled as a multicolor but its patterns dont fade, the lines are crisp (probably a marble, not a multi); its also labeled as a delta/super delta but its a HM (though the tail has curved corners). if you want to check it out go here:
