Reply To: egg -> fry
The article that officially describes the species (downloadable from http://rmbr.nus.edu.sg/rbz/biblio/55/55rbz131-140.pdf) gives about 3-4 days from laying to hatching, and about the same from hatching to free-swimming, but it also says this seems quite long for their kind of fish.
A better answer for all us expectant tank-watchers might be “soon,” eh?
