Unbelievable !!! only 18 days old and already spawning.
Less than 3 weeks ago, Kenneth a friend of mine and also a member in our club told me that he imported some annual killifish eggs from Singapore and he was having trouble in hatching these eggs. He asked me if I was willing to help him as he was very disappointed that no fry had appeared from the eggs he bought.
I pointed out to him that most of the fry from the Nothobranchius species are very minute and difficult to see upon hatching, but still I accepted to help him out. He handed me 2 small packet. One was marked Notho. eggersi and the other was marked Notho. guentheri red. Their hatching date was 10/4/10.
On Saturday,10th. this month, I added water to these eggs and a pinch of micro-worms. Within 2 hours, I could see a few very small fry swimming. After 2 days, they were eating newly hatched brineshrimp and the growth of the eggersi was extremely rapid. Now I could see that there were 6 fry from the eggersi and 12 fry from the guentheri. Part ot their water was changed every 4 or 5 days. When the eggersi were 14 days old, the males were already showing their colours, 4 males and 2 females. 4 days later, that is today, when these fish are only 18 days old, I saw them spawning. I know that annual killifish mature very quickly. They have to do so as if the water body they are in, dries up, there will be no chance for these species to survive. Usually, most of the reports that I read says that these fish become sexually mature in 6 weeks, but for fish to become sexually productive in less than 3 weeks is something that I never heard before in the 40+ years that I have been keeping killies.
These are very challenging fish and they need very small tanks. Heathing is very little as most of them will thrive indoors in unheated tanks. The reward, exitement and satisfaction one will have in brreding these fish, is next to nothing. One can import any species of eggs he wishes to directly from e-bay or other source like the British Killifish Association. Hope that there will be more members interested in these very colourful species.
