Stupid jawfish tricks. "Look! I can balance a piece of sand on my head!" It was there for several hours.

Impressive! I bet YOU can't do that, :D :p
 
A pic of my oldest prolarvae so far. Looks like the initial yolk sac is used up but the mouth hasn't formed yet:

I'm tempted to say that that is why I haven't seen any develop into full-on larvae yet. Especially as the eggs collected tonight are starting to look much different than the first photos I posted. I'm starting to see more fats in the yolk. Maybe as the female is maturing she is starting to produce better eggs?

Oh, and the mandarins spawned again tonight:

At least the Chromis got an extra breakfast (does that make them Hobbits :p ). Those File fish look really fat and happy. Keep up the great work on the Wrasse hatchlings (hopefully :thumbsup: )
 
That video sure shows why survival rates are so low.

At least in my tank. :)

Thanks, Alan! They're too nervous to be hobbits, though. They remind me of little yippy dogs. Though they are also a lot like dandelions: They are popping up everywhere in the system. One's in the DSB tank, one's in the water change tank, one or more's in the overflow, one's in the sump....

Matt Pedersen set me right on the prolarva. The big round spot is not an eye, that's an oil droplet. So, that whole structure is still yolk sac and the worm-looking thingy is the actual prolarva. Lots of yolk left yet after roughly 24-25 hours. The oil drop is extra nutrition and also serves to keep the prolarva oriented head up in the water column since it's very buoyant.
 
Dang it. The mandarins got close tonight but never quite spawned, much to the chromis' chagrins. Lots of ascents but no gametes.

Sorry the image is a little soft. My arms were getting tired and I didn't have enough light for a fast shutter speed.
 
I collected a prolarva yesterday to take a look under the microscope. Unfortunately, the collection did the little guy in. But since it was still enough, I went ahead and made some photo composites.

First, with backlighting:

And with no backlighting:

Those pics are amazing, I can't get over how cool this stuff all is up way way close, thanks for sharing, and keeping me glued to this.
 
got to love that. very inspiring Andy.

Who's those snails doing, and are you going to get us some scope shots of them? :D
 
Well, thanks y'all. Sorry for the double post.

Foods cultures are supposed to be here on Thursday. Then I'll need some time to hopefully get populations established. Then maybe we can really get started on this thing.

Jonathan--Just started noticing collumbellids and the tiny ceriths in the display the last few nights. I'm excited about that last one because I think I only started with two or three individuals. I haven't seen much in the way of collumbellid egg packets lately, but the juveniles from that first big flush are getting big. Hopefully they'll go to town soon. Hmm, how would I get scope shots of the snails? Put them in a small container with lots of slides and hope they deposit a packet on one of the slides? :)
