Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

Dont put too much water in the hatching contaner. I find about 5mm of well oxygenated water over the level of the peat works best you should see less "belly sliders". If too much water is added i find an increase of fry that can not inflate there swim blader.

Best of luck with the hatching,

Is that meant to be 5mm? Or 5cm?

5mm over the level of the peat. Add a more water on the second and third day this simulates more rain fall and can spark more eggs to hatch. Some breeders just put 5cm in the hatching tray and use oxygen tabs to help the fry's swim bladder.

One more tip is to put a bit of moss in the hatching tray or some micro worms this will increase infusoria which the fry can eat.

What species do you have?
Different methods are used for different fish.

I do not find that water depth is a key with belly sliders (within reason). Belly sliders are more due to insufficent diapause consideration (and is more frequently seen in some species than in others).

I use 5 to 6 inches of water and have done that for many decades.

The water used should be mature (irrespective of species); the exact chemical nature of the water will be species dependant.

Mature water gives much better chance of small fry getting food as they need it. Many killifish fresh-hatches are quite large, but some are so small that they will need very small food supplied in mature water within hours of needing it. Not giving them that results in poor quality stock.

Well the best laid plans and all that meant I did`nt get to start the eggs today, but for sure tomorrow
The species I have are Notho Korthausae, I will be using water taken from my 125L tank and have some micro worm culture going strong at the moment, I could use rain water if this would be better

Chris,
Most of the Nothobranchius are soft-water fish - if not all of them.
However, like so much else these days, they have possibly been tank-bred for some generations. If this is the case tank water might be OK, but I always use filtered rain water when hatching Killifish eggs.
I would add that I'm also one of those people, mentioned by Stephen, who uses a quarter of an oxygen tablet when adding water to hatch-ready eggs. I was given this advice by a very successful Continental Killlifish breeder and - honestly - my hatch rate improved right from that time on.
Mind you, plenty of people don't use them and have great success too - I can only tell you that using them certainly worked for me.
I hope you have a great hatch from your eggs - don't forget, you can dry out the peat and re-wet it in a week or two's time and you should get some more eggs hatch.
This is due to a sort of timing device within the batch of eggs - if it rains and they all hatch the rain period mightn't be the start of the rainy season proper so the pools might dry out. If this happens some are 'held back' should the pool then dry out again and there are some eggs in readiness for the next time.
As usual, updates are requested.

Well everybody, it`s been 24 hours and so far no hatch-lings, I have a 1 cm of water covering the peat and a temp of about 23 degC, I have the container on my sump under the lights.
Should I bag it back up for another week or so and try again or leave it for another 24 hours and see how things turn out

I would leave it for another 24-48 hours. Can you see the eggs in the peat? The eggs should have a small black spot in them, this is a sure sign the eggs are "eyed up" and should hatch within the next 24 hours. Make sure you break up any lumps of peat.

When were the eggs collected? It should say on the bag.

Its kinda hard to tell from the pic, but i dont see any eggs there. I dont think them white spots are eggs, if they are the killifish eggs in sorry to say they are infertile or dead eggs.

Depending on the species of killifsih the eggs should be almost clear with an eye of the baby fish visible like in the link below. There are some killifish who have black eggs and black fry but nothobranchius korthausae mafia should be like in the link below.

I would still leave the eggs in the water and if still no fry redry and store the eggs for another week or too and try again.

If, as Stephen suggests, there are no eggs in there don't be disheartened. Believe me I have paid good money for bags of eggless soil, especially from certain sellers, so you won't be alone if it turns out that way.
But - like getting back on the bike after you fall off - please try again. I'm sure Stephen can give you the name of a more reputable egg-seller and I should have a few names somewhere.

But...that's as a last resort - hopefully you'll still get a result with these ones.

Yeah i can recommend some sellers. I will have a look at my egg stach over the weekend, if i have some ready for hatching i will send ya them free of charge. I would hate to have you put off killifish due to a bad seller.

I look at it like this....
you pay 15 or 20 euro for what is claimed to be 30 eggs: they may hatch; they may not; 1 may hatch; there may be nothing in the peat.
you could buy a pair of Nothobranchius or SA Killies from the LFS for 15 euro a pair: they may last a day; they may last longer.

Whichever way you look at it, it is about the same risk. You are also not going to find the range of killifish in shops as you would via eggs. That is the wasy is now, and the way it has been for as long as I can remember (that is a long long time).

I can see one eyed up egg but it's not ready to hatch yet,re-dry
peat for 2 more week's at 75dgs it takes 10-16 week's for Notho Korthausae
to hatch.Google Nothobranchius,look for Tyrone Genade tgenade.freeshell.org
he has a Pdf on Notho's KK
