Hatching Nothobranchius rubripinnis (African Annual Killifish)

I had originally posted this as a reply on here, but decided to make it a thread for queries (if anyone has them).

Here's some of my vids on hatching Nothobranchius killis (ps......the offspring from this particular batch went on to become show winners at several shows :))

All have a bit of blurb about the species at the beginning.
This species is particularly vulnerable and could easily be threatened with extinction.

1...adding the eggs to water (well...water to eggs)


2. spotting the first fry (within an hour)


3. a closer a look at the young fry not long after hatching.


4. Here they are 6 weeks after hatching....front image is of the males at 6 weeks.


As a note, some of this batch of Nothobranchius are still doing well (that is at 18 months old).

Water conditions for these are very mature water. Water changes are done with straight tap water with conditioner (one that contains Vitamin B1).
No salt has been added to any generation of this species during the years this line has been going with me.
Breeding tanks have a peat substrate with added ammonia adsorbing zeolite.
Temperature for this species: is room temperature (whatever the temperature of the room is, as all tanks are unheated. The minimum winter night temp in our front room never really drops below 18/19 C).

A good Nothobranchius species for people wishing to get into this genus as the incubation period is not extensively long and the young can eat freshly hatched brine shrimp soon after hatching.
In some species of Nothobranchius, however (eg rachovii), incubation can be dangerously long, and the fry need (as essential) food smaller than baby brine shrimp from day one for several days.

Hatched within an hour? Wow!

Very interesting Ian.
