Not much is known about the origins of Julidochromis dickfeldi "midnight blue". If they exist in the wild, its location has never been made available. The story I heard about 10 years ago was that a regular pair of J. dickfeldi spawned and some or all of the offspring had the "midnight blue" color. Once two of the new color variant spawn, all their offspring also have the same color. Other than the difference in color, J. dickfeldi "midnight blue" act just like normal J. dickfeldi. They appear occasionally on retailer price lists and would make a great addition to a community tank or a small tank with just the pair.
