Actually, I put the larvae in a little tiny dish, then use a tiny pipette to take out ALL the extra water. Basically, the larvae is trapped, unable to swim or turn around, inside a tiny drop or two of water. Makes the picture process go REALLY quickly, and then just dip the dish in the tank and the larvae (hopefully) swims away unscathed.

Isn´t that clear?.You need a pic?.The pull is gentle and larvae can´t go thru 200 mic.
Overpopulation of rots is very frequent with the greenwater technique.Not a problem with clowns as they´re moved to bbs so early.
You´ll find this collector handy.And you can use the collected rots somewhere else

No kidding?That is exactly how I take pics of my larvae!<a href=showthread.php?s=&postid=8178700#post8178700 target=_blank>Originally posted</a> by mwp

Doug, they're harder to do because unlike the Bangaiis, leptacanthus releases hundreds if not thousands of pelagic larvae, probably on par with most gobies in terms of size. Instead of incubating for 25+ days, it seems that a typical leptanthus incubation is 6-9 days.
Luis, I'm not worried about the larvae going THROUGH the 200 micron, but rather getting STUCK to the 200 micron!

Another round of shots, this is an Apogon leptacanthus larvae at 143 hours post release (basically 6 days, a new record if I remember right). I happened to collect a mandarin larvae simultaneously, so I figured what the heck and shot them both side-by-side. The mandarin larvae is approx. 82 hours post hatch.
FWIW, after lights out when I went to collect the Apogon larvae they were scattered throughout the tank at all water levels. I'm wondering if perhaps they're already taking on nocturnal tendencies!?

Alrighty, I shot these at 1:00 AM, 168 hours post release, aka we've completed 7 days. FWIW, the larvae are getting easier to "see"...for a while there I thought I might only have a couple left, but now there's probably 30-50, maybe more. They're obviously feeding well at this point!
I'd love nothing more than to make it all the way with these...7 days and full bellies...I'm pretty pleased so far. The big question now (in my book) is how long should I keep them on rotifers / when should I start trying newly hatched brine?!

One last set of pics and then we'll have to wait until Sunday night (out of town fishing again...it's that time of year). Hopefully they'll make it in my absence...I'm planning on a good rotifer "filter down" + the addition of a lot of clean water and fresh phyto..hopefully enough to keep the tank cloudy for at least a day (the addiiton this morning is now almost completely cleared out).
So, Apogon leptacanthus larvae at 192 hours post release. The other larvae is a 131 hour post hatch Synchiropus splendidus (mandarin, the last one from that huge hatch).

This morning I had a 'stroke of genius' and to make this story short, I set up 2 2L brine shrimp hatcheries as phytoplankton reserviors using a spare needle gang valve I had around. I added some aeration to keep the phyto in suspension, and currently it's dripping about once every 4 seconds. If things go right, the larval tank should get a mixed 1 gallon dosing of phytoplankton over the next couple days while I'm away, meaning no one should have to take care of them. My only real concern is the valves getting clogged with debris, stopping up the slow, steady supply of food.
We'll find out how it worked come Sunday!
