The article does mention that the young school in the water column along the shoreline after leaving the nest and have fully formed fins and eyes, matching the positions in adults. They are not clear on whether there is a planktonic phase or not, but it seems to imply that there isn't much of one and that they transform into miniature versions of the adults rather quickly.

Any info on the egg size or larvae size there?

Anybody try keeping this species yet? I hadn't heard of it before, but it sounds ripe for a captive breeding attempt.

Not keeping them but I do see lots of goby larvae in nearly fresh water (less than 5ppt). There are some yet to be ided to species gobies mixed in this sample from last week collected in the upper Barataria estuary(excuse cell phone pic) . I've been seeing lots of very fecund female naked, darter, and clowns in our seine samples over the last few weeks. Even in 1 or 2 ppt the female naked gobies were ready to pop last week.Anybody try keeping this species yet? I hadn't heard of it before, but it sounds ripe for a captive breeding attempt.

The larval gobies have a prominent swim bladder. There is a misquito larvae in there for size comparison.

Nice pic! Is that a pipefish in that sample too? And this sample is from Louisiana, correct? Do you think the gobies are spawning in freshwater (or nearly freshwater)?

Yeah it's a Gulf pipefish. These samples were taken just south of lafitte louisiana. I think there are gobies spawning in less than 5ppt and the naked gobies last week were in less than 2ppt and they were definitely in spawning condition. I don't know if they require more salt at some point in their ramp up to spawning but they were spawning in an area that has been pretty fresh for at least a month or two.
