3.6 – Spawning:
Months, days, or hours before a spawning event, both fish will “clean” a hard surface near their hosting site. They will pick at algae and other bits on the surface. The place they clean is where they will lay their nest.
The day of the spawn, the female’s lower abdomen will expand with her egg filled gonads, and her ovipositer may become visible. She may not eat as much as normal. Spawning usually occurs in afternoon or early evening. The female, using a waddling swimming motion, lays a track of adherent eggs on the nesting site, and the male follows to fertilize the eggs. This behavior is repeated for an hour or more until all the eggs have been laid.
4 – Eggs:
Adherent, and may range in color from yellow to brilliant orange or maroon in the Premnas. Egg color may be tied to astaxanthins in the parent diet. Number of eggs per nest may be as small as a dozen, or as large as two thousand.
4.1 – Size:
a couple of millimeters
4.2 – Quantity:
25-2000. First spawns, or spawns after a break from spawning (due to aquarium transfers, death of mate, etc.) are usually small and frequently consumed before hatching. Successive spawns will be larger, and more successful. Some species typically have larger nests, such as A. Clarkii and Premnas. Number of eggs per nest may be as small as a dozen, or as large as two thousand.
4.3 – Characteristics
I don’t think there are oil droplets on their eggs.
4.4 – Incubation period/Hatching temp:
at 81F, 9 days. During this period, the male and sometimes the female will mouth, guard and fan the eggs. When they hatch, the larvae are dispersed into the water column to become part of the plankton.
5 – Larvae: Hatch as free swimming larvae with excellent eyesight, some pigmentation, fin buds, and long tail/body.
5.1 – Size at hatching: 3mm
5.2 – Yolk sac present at hatch: Yes, and is generally consumed by day 3 of life.
5.3 – Mouth present at hatch: Yes
5.4 – Eyes developed at hatch: Yes, larvae have excellent eyesight, and too much light can be stressful to them.

Det er dem præcis i midten af begge billeder.
Jeg må igang med at øve zooplankton og have fat i de bøger, så jeg er klar til næste omgang. Det lader til, at jeg er lidt sent ude denne gang. Desværre - for det er da mega spændende !
Jeg er ved at DIY'e en 4x 20L saltvand/phyto/hjuldyr/artemia klækker, men nogle kloakrør og et 36W armatur fra Harald Nyborg. Så får vi se om den kan komme i gang =) Billeder kommer som projektet skrider frem.
