Simpsonichthys Carlettois

**diablotin** · 4th Oct 2005, 17:50

Hey,
I'm french and I've got 21 eggs of simpsonichthys carlettoi. They are from august 18th.
How long do i have to keep them out of water ? I look at them this week end and i can see now their eyes some are more dark than other.
The tank is a 20L thank i don't how many gallons it is. Their is a lot of plants.

What about the temper and their reproduction ? I know they need turbe but I 'dont know how much.

The will be alone of cours I have daphnia and nauplie of artemia, micro worms.

What do I have to know to make my fish the most happiest ??

thank you for help.

Bye

Hi!
Here in Portugal, we keep them out of water for about 3 to 4 months.
The trick is easy. Just look at the eggs, and when they have "eyes" thay are ready to ake a bath.
It works for me...

Thanks for your answer.
I don't understand very well, you said that I have to wait for 4 month and that when I can see their eyes it's ok but I can already see their eyes...
in which conditions do you keep them ? humidity... I think it is very important to know that as for other fish. For example, ramirezi's eggs'

I join two photos if you can see something and tell what you think

Thank you

Hello, those eggs are not ready yet.

Diablotin,

If you can see the eyes, it's time to wet the eggs. Just dunk them into a hatching tray together with the peat and wait for the fry to appear. I don't know what's the temperature in France now but here in Singapore where it's hot the whole year round, we use oxygen tablets and ice in our hatching trays. You mustn't hatch the eggs inside a 20 litre planted tank. The idea is to use small trays so that it's easy to feed the fry. If you already have microworms, that would be great for the fry.

I'm surprised you asked about reproduction. Don't you know? The fish are peat spawners. We put in a breeding bowl half-filled with peat moss inside the tank and the fish lay their eggs inside the bowl. After a week or so, we collect the peat moss and bag it. When it's time, we wet the peat. If everything goes right, the eggs hatch and the life cycle begins.

If you know nothing about raising and breeding Killies, please take a look at the webpages of killies.com. The information is mostly about Nothobranchius but it's applicable to Simpsonichthys as well.

A better reply from my previous one:

Bonjour Diablotin,

Those eggs are not ready because the iris is not fully formed yet. Only when you see a golden ring around the iris then you should wet them. August 18th is not very long ago. I know of some breeders within France that should have better advice for you since they're in the same country as you are.

**wHeEzO** · 5th Oct 2005, 17:14

I would suggest 6 weeks before first hatching. I'm not sure what the temperature is over there. I've done well with 6 weeks for Simp. Perpendicularis at around 70-72F.

A friend of mine, has the same type of eggs and he is incubating them for 6 weeks first. I believe it's due to hatch in 2 weeks. I'll let you know how that goes.

Hey everybody!

In fact I know a few things about simp carlettoi but I asked as if I don't know really because I would have the most informations it's possible and also compare whith my informations...

So if I sum up, My eggs are too young, I have to wait for the apparition of the corone on the eyes.

As there are very recent, it's not easy to find help.

I think I have all what I need.

If you have suggestions or anything else that could help me...

I will come back to post juste before wetting my eggs and ask you your thinkinings and also for shows you babies

Just a little thing, are the sun or a a lamp (or another light) necessary to help embryons to develop ?

Thank you

A light is not necessary. They should be kept in a dark environment.

Simp. carlettoi tends to produce more males but with some experimentation in terms of temperature and pH, you should be able to produce a pretty good sex ratio.

It is a new species but relatively pretty easy to handle, just like the magnificus. Well, at least that's what my French friend says.

**diablotin** · 5th Oct 2005, 21:09

Maybe your friend is the man who sold me the eggs

Can you tell me just a little more about the consequences of pH and temperature on the ratio?

I have a pH about 6,5 and the temperature is about 24°C I can translate in °F. the gH is about 4 or 5° german so about 9 °TH (french). I have riccia, vesicularia, glosso, echonodorus, vallisneras, alternanthera, it 's wall planted lol

I hope it will be ok for them ...

If I recall correctly from my personal correspondence with the discoverers of this species, it was found in a pond with a slightly alkaline pH.

Didier Pillet visited Guanambi in 2003 with his Brazilian friend and he found that the water in the ponds that contained Simp. fulminantis (also found in the same area but not along with carlettoi) had a conductivity of 1200 µS, pH 7.8 because of the cows that lived in the fields near to these ponds. Their droppings contributed to the high conductivity of the ponds!

I would not be surprised if carlettoi itself lived in similar conditions. It was said that a better sex ratio was attained by raising the fry in slightly alkaline conditions, rather than acidic for some other Simp. species. In the case of temperature, one shouldn't exceed 28°C with the fry but in the wild the ambient maximum temperature was 31°C! I'm not sure if a lower temperature will affect their gender but I understand this variable works with other species but not necessarily Simpsonichthys.

Didier has been keeping and breeding this species for the past few months since he brought back eggs I think from his visit to the KCB gathering in Brazil in the earlier part of 2005. He would be the best person to help you with the carlettoi.

Just for regular info, all of the carlettoi in the hobby are from Guanambi.

"diablotin",
In case you didn't notice, most of us sign off in our names (not nicks) which I feel makes this place much more pleasant, so please don't be shy about it and while you're updating your profile, do let us know where you're from too.

Although the carlettoi is a new distribution in the hobby, I would treat them as most Simp species. In my case, it's 8 weeks storage in a closet at 29ºC and perhaps an extra week or two, if your temperature is lower.

Do resist the temptation to constantly handle those eggs and risking damage or introducing bacterial infection, before the eggs get a chance to fully develope.

Update us again when you see a well developed embryo, with shiney eyes looking back at you.

**diablotin** · 5th Oct 2005, 21:52

Sorry for not completing my profile I'll do it I promes.
And if I don't sign off by my name, it's juste because I usualy sign off by my nick on all of french forum. It my first "english" forum... so I'll sign off Jordan (my first name).

Actually I bought my eggs by internet with a friend but it's didier's eggs... As we were two to buy, it's only my friend who sent him a mail and i had the eggs juste after. He sent us few informations but we have had still questions so we look for on the internet.

What you said is very interessant

I thank all of you.

And I say you good bye to next time with my news killis !

bye

Jordan

**RonWill** · 5th Oct 2005, 22:17

Thankyou Jordan. I really appreciate it.

Good luck with that beautiful species. I'll be making my 2nd attempt soon and hopefully, better results and more fry too.

**CM Media** · 6th Oct 2005, 08:47

Hi Jordan,
This is what I call eye-up and ready for a swim.

After seeing Jordon post. It really got me thinking. Perhaps it is just some mis-understanding. I find this is quite challenging. Is it too late to rush another order?

Ron, i think you might want to consider mimic the exact water condition of where these fish were found. Cows dropping..... maybe some would sell in aquabit....

**stormhawk** · 6th Oct 2005, 10:56

Kee Hoe, there'll be another order at the end of October. I'll keep everyone posted.

This species is easy for some and difficult for others. My experience is limited to the fry only. They have a unique marking on their body, some kind of racing line along the side of the body from the eyes to the base of the tail. Then they lose it after some days. Very unique feature.

I find the fry to be fragile though but I would definitely want to try them again in the future.
