Hi Shaun Ok, I understand your question, both Larvae ar the thame age, newly hatched. The "brighter" larvae (koumansetta) swims in deeper water, it´s nearer to the lense of the mikroskop, and has a bigger distance to the marks of the ruler, so it seems to be bigger. The pic of the dark larvae (Koumanssetta) was taken with an olympus E-620 with macro lense, in a drop of water direkt on the ruler  hope you will understand, what i try to explain ... very bad english  LG Lars

What everybody had suggested, comes true: They are to small to eat "normal" rotifieres. The video compares the new born larve with the rotifieres and of course, one more pic from last night. Now they are, 17h old, a lot of swimmers. This time in a black bucket (5l) with a lot of Phyto and rotifieres and the Video: http://youtu.be/K6Y8qEJ4QHc Lars

Maybe my starving experiment from the first run was wrong. Now they live over 22 hours and they are still alive (quite a lot). Ok, this time I use the black bucket and much more Phyto (Nanno and a big shot of phycopure) The hole day i gave little amounts rotifires but they don´t eat. I checked it under the Mikroskope: The bellys are emty. Lars PS. Just discoverd the breeding journal of wdt (k. hektori) the observations are quite the same.

The second day is almost over (46 h) and there are still a lot of survivors I´m very happy (or satisfied ??-- language problems  ) with my small BRT. Phyto dense ist high, I can see 10 cm deep, 24h lights are on. Of course there are a few dead larvae, but the most are still alive Lars

A lot off dead fish, but some are still alive Last night i had a hatch of my occis (Darwin). I didn´t collect them, but in the morning I put a dead occi larvae together with a rainfordi into a petri dish and made a Video : http://youtu.be/LDVcIob4jtg Lars

Wow, that size comparison is something else! The first eggs I ever hatched were Dottybacks, and after that I thought Clownfish larvae were huge. It looks like the Rainford's Goby larvae are smaller yet!
Don't let fear and common sense stop you! =]

Hi Mindy Yes I think you´r right, they are smaller than dottybacks. I bred assessors and they are also bigger than the rainfordi The third day is nearly over and there are some survivors left. But now I have to stop the airflow and have to search with a torch to see some aktiv swimmers Lars

Ok, Game over! I can´t see any moving larvae. But I´m not disappointed with this first run. I´ve got experience and some nice pics. Lars
