This spawning pair was acquired from a friend who was breaking down their reef system. I was told the fish originated form Proaquatix a couple years ago via his LFS, that is why I am assuming they are E. randalli (Proaquatix) instead of E. figaro (ORA). If anyone thinks different, please let me know. Picture of broodstock:  Spawn:  Video of hatch:

  Some side shots of broodstock...needed confirm (or refute) the species ID. Again, stock is from Proaquatix, so my assumption is E. randalli, per their website. I welcome your opinion...after all, it would be nice to market this beautiful species properly.

OK, so according to Humann's book, the diagnostic between randalli and figaro, beyond the geographic separation, is this. E. randalli is said to have a "thin bluish stripe (that) runs from under each eye to behind the pectoral fin". This is not noted for E. figaro. In Humann's book, you can clearly see the blue stripe in one of the two fish photographed, but not the other. I cannot see the blue-ish stripe on either of your fish, but that could be the angle of the camera / lighting. So this may require your personal observation to make the final diagnostic. Now, we know that at least two species have color variants (Sharknose and Neons) so that could further muddy things, but I discovered pretty quickly several good photos of Randalli that show the blue stripe. Here's some links: http://www.natuurlijkmooi.net/images/elaranc.jpg http://reefguide.org/pix/thumb2/yellownosegoby2.jpg http://upload.wikimedia.org/wikipedia/commons/thumb/1/11/Elacatinus_randalli_bonaire.JPG/400px-Elacatinus_randalli_bonaire.JPG http://www.luizrocha.com/fish/E_randalli.jpg And here are some E. figaro links http://upload.wikimedia.org/wikipedia/commons/6/60/Elacatinus_figaro_RZPG.jpg http://www.sgreefclub.com/forum/uploads/post-36-1080104829.jpg http://gobiidae.com/sp_pics/ELACATINUS_PRIDIS_01_JLG.gif http://reefbuilders.com/files/2011/03/yellowline-goby.jpg Now, my understanding is that E. figaro is no longer accesible as a wild caught fish since it's blocked from export in Brazil (it's native waters). I also think that, from what I can see, your fish look more like E. figaro than E. randalli...and if that's truly what you have (E. figaro) that's great because if we lose it in captive breeding we'll never get it back. So the questions to ask would include going back to Proaquatix and seeing if they know the provenance of their broodstock. Note that ORA produces E. figaro, not E. randalli - http://www.orafarm.com/products/fish/gobies/yellowline/. Also note that Proaquatix's one small photo does not show the blue line of E. randalli. - http://proaquatix.com/html/goby-yellownose.html I wonder if you have E. figaro, and not E. randalli.

That is correct ! E. figaro is listed as endangered in Brazil and hence it can not be legally exported. However I have seen it offered for sale around here as E. oceanops and E. randalli some time ago as I have seen Gramma brasiliensis (also endemic and can not be exported) offered as G. loreto... So, it can not be legally exported but do not take this as a criteria to exclude E. figaro as a possibility when found at wholesalers as it may still happen with mislabled illegally exported fishes. Back on track, these fishes look more like E. figaro.
