Since I have only 1 female, it is possible to record the birth-interval
On the 23rd of december I saw the first young of this pair (4 initially survived, now 3 left), I believe that these are the first young of this female. When I caught her she was rather small (about the size of the male, less than 2 cm).
On 6 January I noticed a single young, which looked newborn (survived for some days)
and then, on 18 January I noticed another 3-4 newborn platies (6 survivers, but I have difficulties counting them because they are usually hidden in the vegetation).
edit: on 9 February I witnessed the birth of the next litter (6 seen, probably have been more)
edit: next litter: 7 March
The water temperature is about 26'C. Note that these seem to be small litters, but the mother could have eaten some (other fish in the aquarium: some half-grown guppies, Corydoras paleatus and Ancistrus "sp3"). This is a much shorter interval than 1 month (1 month is usually mentioned in literature). I suspect superfoetation, but is this known from platys???
After giving birth the female looks pretty much equally round as before, which makes me suspect that the litters are really this small.
The young look uniform pale brown at birth, time will tell which colour they will have later on.
Edit (13 March): I have very poor survival rates in the young, from the first litters I have only 3 males left. Lowered the temperature to 24'C.
