I had to put that in the title, because I am not 100% certain what on earth it actually is, but it's spewing out eggs as I type. Unfortunately, I can't say if it is spawning due to being a good thing or a bad stimulus/i (but hopefully good). I'm watching to see if any others follow. I'd get a pic of it, but I've been extremely lax with the coralline scraping as of late. I wish it would've waited until tomorrow, which is when I intend to change the water and scrape the glass.
