Nice! Thank you for the photos!

I have a Mated pair of Diamond Gobies... and they have setup shop under the rock that is under that pile of sand. I'm not 100% sure on the spawning habits of Diamond Gobies, but the few vids I have found on youtube would suggest this is what they are doing. The Male builds a mountain while the female stay in the burrow.

While very cool that they are spawning.... aesthetically, it drives me up the freaking wall! I typically end up bulldozing it and putting the sand back where it belongs.

Even as I sit here at my desk, I can see the male working away on that mountain, mouthful by mouthful....
