This species was originally classed as Aphanius mento Zengen, but now has been changed to Paraphanius similis Zengen. Though still a stunning little fish when the males are in full breeding colours.
Well last year I had some of these outside in a plastic container and more or less they were left to their own devices. When it came time, in October, to bring them indoors, I found that the adults had disappeared but I had about a dozen young adults. Now these fish over-wintered in the lowest (coolest) rack of my fishroom, and just recently I have noticed that the males were showing intense breeding patterns. I must try to get some pictures of these fish so that people can see what they are like at this stage. There are a number of males in the tank, but they seem quite peaceful which is a good thing. Well I have watched these fish for a few days, whilst doing the other million odd jobs that need doing in the fishroom, but tonight decided that I would check for eggs. To say that I was surprised is an under-statement as I stopped counting when I got to 50 eggs. So these are now in water with Acriflavine and Methylene Blue added and I will put half of them onto the cotton wool pads in a few days, to see how they cope with mode of incubation. Future updates to follow as part of my experiment.

Sorry that I have not been very good in writing on this "Blog" but things have been uneventful in the fishroom. Just doing lots of feeding and water changes.
Now though I have started to use a new system for storing eggs from my non-annual killifish. The picture above shows Scriptaphyosemion cauveti eggs that were collected on 5/3/21. The full article can be seen under the heading above, "Articles ==> New System for Egg Incubation". Have a read and hopefully it may give you some ideas for you to try yourself. Now this was not my idea originally, but based on an article by Tyrone Genade in the Oct-Dec 2020 edition of the Journal of the American Killifish Association. The original article was on shipping non-annual killifish eggs and the best method to do this. I have adapted this slightly for incubating killifish eggs (mainly Fundulopanchax) in my fishroom, and I will be very interested to see how this new system compares to the damp coir/peat or water incubation methods. I might even try selling a few eggs later in the year, once the weather warms up a bit more, and will use Tyrone's method. |
