Unfortunately I lost one of the males. I found it dead in a corner. I can't see anything strange on the body. Maybe the two males had a fight over the females, because... it happened! Eggs for breakfast! There's not a lot of room in those small pipes. Maybe I should get bigger ones?  There are eggs all around the pvc pipe. I guess about 100 eggs.    The male is guarding the eggs and fanning them.  |

The male was just harassing the other fish, so I sneaked to it and quickly took a picture of the eggs. It's just wonderful!  |

I would not get bigger tubes. At 1st I thought the tubes were a bit too big, but I can see the fish have grown. But...there is still enough room for another fish to get in there and gobble some eggs. Or times when he's running one fish off, another might sneak in and grab a snack.
Another possibility is that he might decide to spawn again before this one is done. Which leads to them clearing out the current eggs to breed again. I've had mine "group spawn" but that is usually with multiple females over the course of a day or two. Looks like this one is well established. But with it being his 1st attempt and hormones high in the tank, it's possible he could do this.
In my experience, the males do a good job of defending the eggs once they figure it out. But as soon as they begin to hatch, the others will be all over there eating the little ones.
Best to move the tube before they hatch. Just put an airline with an airstone in it to simulate the male fanning the eggs. If you see any white eggs, you can carefully remove them with a small pipette or tweezers.
When they hatch, they are just about the right size to eat newly hatched baby brine shrimp, or ground up sinking pellets. Live is better. You can also feed vinegar eels, and other nematodes like Walter worms, banana worms,etc. Moving the tube to a well seeded, mature tank is good, because the little ones will nibble through the algae and biofilm.
Good luck! :-)

Thanks for the advices. Indeed I was thinking to get the eggs out of the tank when they are a few days further. I really like to have some offspring so that I have some spare fish when the parents decide to leave this earth... I couldn't find any lifespan of this species. Do you know it?

The lifespan of these gobies in captivity seems to be about three years. But I guess that depends on how well they are looked after?

That's what I've seen as well. 2-3 years. I unfortunately lost mine this winter while out of town for about 6 weeks on a family emergency. The temperature in their tank dipped down around 65-68 degrees F while I was gone and they died. Over-feeding could have played a part too.

It looked to me that eggs were disappearing either by the father or by the snails. So I had to take the tube out of the tank and put it in bare tank with some water circulation through the tube. It's kind of sad to see the father now looking for his offspring. But on the bright side: there are some fertile eggs!  |

Somehow these eggs do remind me of the movie "Alien". I'll have to keep an eye on this...  LOL. Yes! Watch out! They will take over! Hahaha. |
