hmmm. Not many. Just the rock kribs.
Pet stores have been known to sell any of the Pelvicachromis species as Kribensis
including Pelvicachromis subocellatus and Pelvicachromis taeniatus. My LFS is currently selling a Krib-like fish as Kribensis and while I haven't yet to figured out exactky what it is it certainly isn't Pelvicachromis pulcher.
I'm not being argumentative I just think scientific names keep it clearer. You should post a picture.
