It's good to see there are more species available now. I'm not sure I'm too fussed about the indigo dottyback (Pseudochromis fridmani X sankeyi), particularly when there are so many much more spectacular species out there without resorting to hybrids. It's good that P. elongatus is readily available, but there are quite a few other small, relatively common species that don't seem to make it into the trade (or at least not with any regularity). Do an image search on some of the following to see what I mean: Anisochromis (there are four species, including an undescribed one, all of which only grow a little over an inch; male Anisochromis kenyae are particularly cute - Image from FishWise Professional - Encyclopedia of Life
); members of the Pseudoplesiopinae (Amsichthys, Chlidichthys, Lubbockichthys, Pectinochromis and Pseudoplesiops .... most are well under 2 inches), and some of the smaller Pseudochromis (P. striatus, P. luteus, P. coccinicauda, P. cyanotaenia, P. melanurus, P. tapeinosoma). Perhaps some of the commercial breeders could source breeding stock to make these species more readily available.
