Diamond gobie eggs?

ddc0715 · Jul 24, 2021

So I have 2 diamond gobies. Bought at differnt times. Anyway saw this today. Have they spawned? Not sure why one it dragging this all over the tank.if true wow. Do I just leave them be?

They are just laying on the sand bed

So cool! Leave them be. Nature will play out just fine. Everything in the tank will get an ice meal once hatched.

My goodness. . . Never seen this in captivity. Unfortunately, there appears to be no male to fertilize making this Caviar for tankmates which is actually healthy food for them.
As @DeniseAndy stated, do not disturb and see how long they last and play out. May be time to add 1-2 more gobies which should get along and see if any have an interest in getting married to her and have children. . LOL

Would they need it? Perhaps this species is capable of parthenogenetic reproduction.

As I said I have 2 of them one Isway larger than the other but I do t know if ones a male or not. The smaller o e was the one that was dragging them around. I have a theory but it's just that a theory as to why these were drug out from somewhere.

Could be a mated pair at this point. Super amazing. Let us know if it happens again.

I recently bought a pair, and like yours one is bigger than the other. They rarely stray apart from each other and in fact spend most of their time right next to each other and sift the sand in unison !

I had a pair that would spawn regularly, but never saw them drag the eggs around like that. These were bright orange, also.

Ours breed regularly.

That's consistent with what the eggs look like but the behavior you observed is unusual compared to what we see.

Usually they dig out a cave under the hardscape. Male & female close themselves in for awhile, spawning. Female leaves the cave and seals the male in. Male stays in the cave for a couple days before emerging. I've never seen him relocating the egg mass.
