In an unexpected surprise, my Diamond Goby pair, or Valenciennea puellaris, have laid a successful spawn of fry. Probably their 4th time or so, but I never attempted to recover eggs at hatch time. In this case, I was able to dig up the eggs that were developed enough to hatch as I was disturbing the nest. There were at least several hundred of them but at this time I have no way to feed them so for the most part they are Banggai Cardinal food. Now that I've confirmed the spawning I'm considering preparing for the next spawn.
In other news, tomorrow I'll be bringing my first full batch of Banggai Cardinals to a store on consignment and hope they find good homes.
