Breeding L128

[furrfred]

Hi Guys

I'd like to share pics of my newest fry with you. Today, seven fishes did hatch, and there are 47 eggs remaining. Hopefully, at least some ones will grow up healthy.

Very nice. Did you extract the eggs and are trying to hatch them without the male? Is that why they're on the substrate?

Oops, I see that they are fry with yolk sacks.

Can you provide some details of the breeding setup?

[furrfred]

Hi

Thanks guys!
Here some information:
- There are 4 fishes, TL 16-17 cm. 2 male, 2 female.
- Tank is 100x40x40.
- Swiss-water without any treatment, about 300 microsiemens. Temperature 29 Celsius.
- They did already spawn last year in march, but eggs disappeard after 3 days.
- By the end of 2012, i saw a pair in front of a cave (normally never the case), so i did two water-changes of 50 % with same water in two days. On third day, there were eggs.
- I took the eggs out of the cave on the 2nd day, and tried to hatch them "manually" in 30 Liter of 100% freshwater (each day replaced, incl. tank), temperature relatively low. It took up to 9 days until most of them did hatch.
- Currently, there are 41 that did hatch, and 12 eggs remaining.

Enough for the moment?

Regards
Fred.

I wonder if part of the problem is that they're being kept in water that's too cool. The Cat-e-log says 22 - 25 and furrfred's report and others I have read said they bred in 28 - 30 degrees C.

these are my favs, so wishing you luck and please keep posting updates ! thanks,Georgie

Hi gents

About the temperatur, in my view the cat-e-log is completely wrong. I woudn't keep these fish at 22!!!
The whole summer i did keep them at 26, and there was no breeding activity at all. In the winter, i raise most of my tanks to 29 - 30. You can see how the fish like this raise, and quit it by more activity. So in my view, cat-e-log should be adapted, see also http://www.l-welse.com/reviewpost/showp ... roduct/140

By the way, all of them are out of their eggs now. I count 52!

how are they doing? any updated pics ? Hope they are doing well. Georgie

[furrfred]

Yes, they are doing very well at the moment. They are still all 52 alive! But have no new pics

I have altered the recommended temperature for L128 to "25-30'C" - will be live as soon as Jools have vetted the data.

Thanks Mats!
Update: They are still alive, all of them.

Wow, they still have full yolksacs?

[Suckermouth]

Ooh look at all the little cutie pies! Congratulations and good luck!

What are those snails?

[MatsP]

What are those snails?

Malaysian trumpet snails, as far as I can see.

oh, so adorable, and the blue shows up right away ! They are gorgeous babies, and please keep updating with photos..makes my day ,thanks Georgine

Hi all,

Malaysian trumpet snails, as far as I can see.

Definitely MTS (Melanoides tuberculata) Ingo Seidel uses them as egg and fry "janitors", there is a description of this in "Back to Nature Guide to L numbers", and some discussion here of egg safe snails:

Hi

Here's a new pic. Unfortunately, it doesn't look good at the moment. I already lost 16 of them the last two days. Seems to be a problem with their yolk sack, which doesn't goes smaller, and becomes white at its end. Because i used every day 100 % freshwater, it is not a problem of water quality. The only change that i could see was that temperature increased. But i am not sure at all if that could be the reason.
Seems to be a known problem with Hemiancistrus. If somebody has got a solution, it would be great


Cheers
Fred

[2wheelsx2]

Sorry to hear that. So you think the temperature being too high may have caused them not to utilize the yolk sac?

[zeebo]

hi, not sure if this will help, but i went back reading the old threads remembering someone was sucessful in breeding L128's ,so I found the thread on page 53 ,scroll down about half way, and look for "L128 blue ghost" . there may be some onfo there to help you. Also, i recall in the now defunct site someone keeping a daily journal, and remember he took a very thin paint brush and daily brushed the yolks very gently to remove any fungus. He was also sucessful. If you raised the temp, what about adding more air stones ? that is just my inexperienced addition. Good luck and hope they make it. Georgie

I had this problem with L200. I only had a few survivors! They also started to have problems at the stadge that yourse are in now. Unfortunately I dont have any solutions. Among with L91 this is the most sensetive fry I ever tried to raise.

As much as I love the new HOT fry savers, I am thinking they may harbor bacteria too well. I noticed the OP put a layer of sand down to help alleviate the problem an that often helps, but I have only been successful raising hardy fry in them, so far. Rainbows don't last for me, but Ancistrus and a couple Cory spp. do fine.

I suppose the obvious suggestion is to try letting father do the work next time.
I hope some of this batch will pull through. It's an achievement to get this far with a rarely bred species.

[furrfred]

Update: As expected, all of them died. Let's wait for the next chance...
