Overview The first spawn was on Tuesday 28th of May 2013. The breeding group consisted of 5 males and 1 female. The smallest male was at least 25mm SL and the smallest female was at least 30mm SL. The youngest adult was approximately 5 months old. The individuals were obtained from Aqua Forest Aquarium in San Francisco.

Furniture Big branch, narrow-leaf java fern, 2 regular java ferns (with gnarly fat rhizomes), a bunch of Blyxa japonica and some small hygrophila shoots. Small-grained (but not quite sand) "Congo Sand" by Aquarium Nature Goods with larger, more pebble-ey "Congo Sand" by the same guys.

Behaviour The males were pretty frisky. Zipping all over the tank, nuzzling and chasing the female (and the male guppy, who wasn't very interested). I saw the female briefly enter the T-position before depositing an egg. The males look the same as always, the female looks seriously rotund. The eggs were deposited on various places on the glass.
Eggs There were 7 white eggs laid which were 1.0mm in diameter.
Segregation I'm planning to leave both parents and eggs in the main tank, mostly because there's no other tanks to put them in. One is being used to culture Daphnia, the other is still cycling and that's no good.
Fry sizes 7 days: 0mm
14 days: 0mm
21 days: 0mm
Juvenile sizes 1 month: 0mm
3 months: 0mm
6 months: 0mm
Fry and juvenile feeding No fry hatched yet, but I'm culturing Daphnia in preparation. I'm also planning to add foam head to the filter intake instead of the slotted one for both microbes and safety.
