So I caught a couple of clown gobies out of the Laguna Madre over the weekend and lo and behold, today I have eggs! Oodles of them! Now to grab some rotifers from school...

Well, probably nothing like what you're thinking! These are Microgobius gulosus. Here's a pic, not mine though: http://investigacion.izt.uam.mx/ocl/Peces/Fotos/Microgobius%20gulosus.jpg

Nice fish, good luck. For a little reading:
Parental care and reproductive behavior of the clown goby, Microgobius gulosus, with observations on predator interactions
Author: Gaisner, Ana
Source: Environmental Biology of Fishes, Volume 73, Number 4, August 2005 , pp. 341-356(16)

Abstract:
Describe reproductive behavior and mating system of the clown goby from field observations. Clown gobies exhibit a loosely haremic mating system. Pairs construct burrows at the base of cattails, the roots of which provide structural support and a spawning substrate. Larger males monopolize multiple burrows, each with an individual female. After spawning, males camouflage burrow entrances with sand and females brood developing young for 4 days. Males continue to guard the covered nests in 50% of observed brooding periods. Burrows are also used as shelter from predators. Both sexes confront intruders but only males exhibit a distinct color response to juvenile blue crabs, Callinectes sapidus, the most significant predator. The male color response appeared to mimic the color of adult blue crabs, a known predator of juvenile crabs, perhaps acting as a deterrent. The presence of the predatory blue crab may require one parent to perform deterrent displays, promoting female care in this mating system.

I don't anticipate much luck with this batch, since I was completely unprepared and didn't have a rotifer culture going. That, and I'm heading to Houston for a couple of days. Hey stoneroller, thanks for the citation, I'll be sure to get that article as soon as I get back!

Yep, so just to update, my trip to the convention in Houston pretty much spelled doom for this first batch. They haven't laid again since, so I've got to put them on a light/temp schedule to see what I can do.
