Neither one; the two fish in the hobby that are commonly called "bimaculatus" and "lifalili" are most likely different populations of Hemichromis guttatus
. The real H. bimaculatus
may not even be available in the hobby, at least in the US. Anton Lamboj, who wrote the book on West African Cichlids, leaked at the 2007 OCA show that the real lifalili
is a red and yellow fish similar to cristatus
, but he apparently hasn't written the paper yet (at least, not that I've heard).
There are currently 8-9 valid described species of "Red" Jewels, and several populations that are currently unassigned or undescribed. These fish tend to be quite variable in appearance, leading to considerable confusion as to ID in the hobby. The Forest Jewels, such as cristatus
, are much less aggressive than the more common guttatus
. IMO, cristatus
is much more colorful than the solid red species. You might want to look at the genus here: http://www.cichlidae.com/gallery.php?genus=Hemichromis
The bright red populations of guttatus
are usually assigned the name "Lifalili" in the hobby, so if you buy fish under that name you should get the reddest forms. But even those really don't stay completely red all the time, only when breeding is the color so intense.
