I am very excited to get this pair. They are beautiful little gobies and were paired by the illustrious Kathy Leahy. I am sure they will be ready to spawn soon. We thought there was perhaps a difference in the nose color between the sexes (as shown in pics below) but today they look exactly the same.

We have spawnage!! The female was extremely plump and the male was really working to coax her to the pipes (actually between the pipes). The video shows the way he was acting towards her pre-spawn. They had been sleeping together between the pipes the last couple nights. I guess they liked that spot. Interesting though that they laid the eggs on the floor though instead of either pipe.

Is that netting I see? Withing the 10 gallon tank, do you have them isolated in a breeding cage or something?

Yes that is netting. I just got them from Kathy last Thursday so I put them in the net to get the settled and adusted to my feedings. I hope these eggs make it. Would be nice to know I have some juveniles in hand before I release them to the display. I didn't think they would spawn quite this fast though. Kathy is the fish whisperer!

Daniel, you've done everything right, and now you know the wait was worth it! I thought several times while I had them that they were close to spawning, but at last they did it, and in the right hands. Congrats, so happy for you!

Thanks Kathy. It's good to be back on the wagon and actually have some fish spawning again!

So they spawned again on Sat Aug 29th. They spawned at 11:00am as I checked them before leaving the house at 10:30 and noticed the make doing the same nudge and dash as she on above. I thought that Saturday would be the day they would spawn. I assumed they would spawn in the evening and assumed they did last time with the main light off but ambient room lights on. When I returned home about 11:30 the eggs were there. I bet they spawned in the morning last time too. So I have to confirm which is accurate. We did lose power for several hours On Fri the 28th and the lights came on about an hour late. Not sure if all this made them do things differently or not. I guess the next spawn will tell.

So the last spawn dwindled away a little each day and none appeared to make it to a hatch. Hopefully this one will. There are definitely more eggs this time. Here is picture for documentation, it's a poor photo but hard to get a good exposure and focus pointing up into the lights.

Got a hatch this Saturday. Hard to get a pic of these guys but here is a video of the reflection of the flash light. They all had 2 reflective spots. Here is a picture of the eggs just prior to hatch.

Thanks Joe and Kathy, and Ken from above! I counted at least 6 still alive last night, probably a few more. Its hard to find these little buggars! It's like you have to stare at the empty water for 5 minutes before your eyes start seeing them! I will get a better count tonight and maybe a better pic of a real larvae tonight. I hate to remove one to take microscope pics since I have so few left but maybe if I use the good camera and use the window I left unpainted for side viewing I can get a decent one.

I counted last night quickly and saw probably a dozen or so. They are roughly double the initial length but still look the same. I was able to get 1 crappy picture of one that at least shows the form from the side. One thing I have found during trying to research the larval development is that there doesn't appear to be a good photo documentation of the larval development day by day (expected there wouldn't be for evelynae but was surprised to find that neither was there for oceanops). I now accept the challenge of completing this documentation with a future batch.

Keep it up! Looks like 2 larvae in that pic - one close, and one right over the 4 on the PVC pipe. Are you using just Parvo, or any s rotifers?

Ken - good eye, that is a second. Or was, it's a dead one. I don't have the tank in a very accessible spot and from the top didn't see it there when I was siphoning. It's gone now, and I finally took out the pipe too. I have fed them strictly parvo to date. It's so nice using pods and live algae. The maintenance is much less and I don't have to worry as much about keeping the pods enriched, although I try to. With the small number of larvae the parvo is self sustaining and I think I am even going to have to sieve a bunch out to reduce population to get more naups. I have another hatch Friday and I am planning to run multiple batches since there are so few from this batch. I was a little late splitting my ISO this last time and it's not immediately bouncing back so I am a bit nervous but I think I have that down now, consistent rhythm is the key. Then once you have Iso and it sinks in how absolutely little it takes to feed the parvo it's all pretty simple. Thinking about not bothering keeping S rotifers (or any rotifer, even for clowns!) anymore at all and using the CCS I have to try on parvo.
