There are dozens of different colors that the favia family come in. Can't say i saw what with that particular markings, but new ones are found often. It is well named. You may not find anything on zebra favia because that was more than likely what the seller named it. Its care would be the same as others in favia family.
Could you get a better picture it determine it is a favia and not an enchinata.
Thats the reason i got it...i have not seen one like this before, i got a good price on it and a couple other things and the name does fit it but as you said it is probablay just a seller name my lfs gave it, i wish you could see it under blues it loons amazing
