I have a pair of Diamond gobies that I thought might breed eventually. I have no way of telling if they are a male-female pair, buy they have bonded really well, and I was hopefull.

Up until last night they both seemed fine. However, this morning, only one came out from their shared overnight burrow. I cannot see the other anywhere.

What is really strange is that the ALWAYS leave the burrow entrance open during the day. However, today, it is sealed up with larger rocks and shells.

Could the other goby be sealed inside intentionally due to spawning?

Any comments from anyone who has experiece trying to breed these fish would be helpful.

Thanks!!
