Pseudacanthicus sp "black" - a breeding tale

[Haavard Stoere]

I am sure many of use myself included are very interested in Pseudacanthicus breeding, so keep posting about your progress. Sorry you lost the last batch, but you are likely to get more spawns this winter.

You should maybee keep some juveniles for yourself to see how the spotted pattern develops as it may be important for identification.

Hi

It looks like this species Pseudacanthicus sp(l097), the amount of white spots is very individual and with age they loose most of the white spots

thanks a lot for your submission... So you think my Pseuda are L97

L97 dont loose the white Spots. I have L97 wit 20-25 cm wit hundreds of brilliantly spots.
I think this is L320

Congratulations

news from the "Pseuda" front :

Another stimulation in late October and immediate results in the first week of November... a new spawning ! The male did a good job during the first 36 hours but then, he left the clutch for hunting a L128 male which was too close to the cave... This done, he wasn't able to go back to the cave during at least 30 min... Another L128 big male took interest at the cave and began to go inside, starting to eat the clutch... I was there, aware of the situation, so I had no choice but taking the clutch out of the tank in artificial care...

here two pictures of day 2 (1st day of artificial care : Friday Nov. 7th)





as usual, after a few more days some eggs began to catch fungus or something so... I had to explose them to save the others... I use a syringe to inject water inside them... it works quiet well... doing it I accidently made hatch 4 eggs on day 5 (Monday Nov. 10th)... those last, of course, died within the next hours, as they were not full developped...

and this morning at 6 am I saw that the first "regular" hatching was processing I'm going back to my tanks now, just to see the evolution... I'll give you news tomorrow...

L97 dont loose the white Spots. I have L97 wit 20-25 cm wit hundreds of brilliantly spots.
I think this is L320

Not all adults loose their white spots but many does, I still think they are L97

This was a great read. I can't wait till my L273 are large enough to breed. Can someone recommend a book to read on
Pseudacanthicus and their breeding requirements.

[Cattleya]

Hi Janne

Not all adults loose their white spots but many does,

Real L97 do not

look at the Juvenils


L97 Jungsters looks close like L241
or like this "13cm L97 from Ingo Seidel (aquaglobal) "



i am shure the Pseudas from Eltofi are never L97

Lg Udo

[ElTofi]

I still don't know exactly who they are... but I can tell you they're must be from Switzerland, genetically punctuals exactly 7 days at 28°C and... HATCHED !

[lgb]

one thing i dont know, why dont let them be breed in the tank, like in natur? i know you might not get so many, but still

[Cristoffer Forssander]

L97 Jungsters looks close like L241




I have to disagree! I breed L241 and they have much bigger spots then that. There are several more differences, fins and so on...

But I don't know what species this is...

[Cattleya]

Hi

Code: Select all

I breed L241 and they have much bigger spots then that.

yes i know ! But closer ;)
and it is black as night (both) an
and starry sky (both)

puh...
sorry for my english.
I can not express in English (google Translation English ;) )
believe me, this is not L97 or let it remain

one thing i dont know, why dont let them be breed in the tank, like in natur? i know you might not get so many, but still

I had a problem with this really spawning... the male quit the cave because of another male L128... and as another L128 was beginning to eat the eggs after a while, I had to take them out of the tank for an artificial care...

In German for Udo (at least a nice try) :

Udo : ich wäre froh wenn du bei mir kommen wünschtest, um diesen Pseuda zu sehen, und vielleicht endlich klar nennen können Das ist eine herzliche Einladung...

Well, you're an expert on Pseudacanthicus so its a bit hard to disagree with you!

[Cristoffer Forssander]

I really have to learn how this quote thing works...

[ElTofi]

like Britney use to say : "oops, they did it again"...

so this time, if I don't make any mistake, I'll be proud to show you pictures of the growing of them... You already had the pictures of the fry during the 2 first weeks... so this 2 pictures have a bit of "already seen on TV" taste... but I will give you some new pictures in about 2 weeks...

waiting for that, here are the today's pictures (day 3 after hatching) :




see you in a few days...

Tofi

[Cristoffer Forssander]

Amazing images!!!
There must be over 100, right!?
Hope they will do just fine!

Keep us updated!

[crocodile_pleco]

Fantastic photos.

I hope they reach the maturity and we can see them.

Good luck.

[Haavard Stoere]

Very nice etsy :thumbs up:

Could they be L065? This Sunday I got some L65 juveniles from a German breeder. Most of mine have larger blotches, and some have spots, the spots are not as small as on your juveniles. Adult L065s look very much like your adults. The low aggression is also typical of L065.

[Cristoffer Forssander]

L065, that big? They normaly don't grow bigger than 20 cm... but, I'm not sure what species this is.. I've been wrong before.
There are some suggestions for sure!

Regards
Cristoffer

L65 Pseuda variegatus was one of the first possible ID I checked...

On http://www.L-welse.com someone told me they certainly were L65, based on a very similar picture... But Yann Fulliquet has another opinion, and so have I, mainly due to the size and to the colours of the youngsters...

As soon as the youngsters reach a 3-4 cm size, the colours don't match with the L65 youngsters... the white spots are too small on mine... On L65, it's more like "SchneeFlecken" (hold on a moment, I check the right word in my dictionnary) : snow flakes, irregularly on the whole body...

But thanks for your contribution. This week-end, I'm gonna catch the female to take new pictures...

[ElTofi]

hi all,

a few pictures... first of all, the youngsters at 7 days I'll soon be able to count them... maybe in about 10 days, I will transfer them in the 160 liters waiting especially for them to come in...



Then, I want to show you the female. Do you remember when I told you that the male was biting her, wounding her belly ? On this spawn, it seems that the same happened. Tonight, I take her out of her cave, just to have good pictures of her.

On this first one, you can see the wound, 15 days after the bite. It's getting better, but it's exactly at the same place than the last time. I wonder if it's not dangerous on the long term ??? The skin is very thin and tender, and I won't be surprised that it could become a problem after a while...



I took a few more shots to try (still) to ID this Pseuda... this female is exactly like the male, except on the size. She's much smaller (15 cm only, for 23 for the male). First picture for counting the rays on dorsal fin :



and finaly, the entire fish, in a defense posture :



I'm waiting for your comments either on ID or on "possible medical care" for the female's belly

thanks

[Cristoffer Forssander]

I think the biting is a part of their behaviour!
I've seen similar behaviour in Leporacanthicus... perhaps not in the belly.

[ElTofi]

Hi everyone,

I had ID informations about my Pseuda from Ingo S. based on pictures... Actually, we still can't say who they are... But we can say who they are NOT

According to IS, the adults look very similar to L65 or L320, but comparing the pictures of the fry, the coloration and white spots don't match.

For L65, the doted pattern is much less regular and the spots are not so round and precise.
For L320, IS saw lately some fry and if they also have white spots, those aren't so clearly defined...

So exit L65 and L320...

IS heard about a new Pseuda sp from the "Alenquer area" and he will check this by a "L-addicted" in the US who has the same Pseuda as mine (or the opposite)... it seems that this one could match... the point is to be verified by the youngsters coloration. I hope to have news soon...

[ElTofi]

hello all,

3 picts of the day... youngsters at 7 weeks... everybody's fine, and they are around 200 little guys in there...







see you soon...

[andywoolloo]

just amazing! they are so beautiful! I can't even imagine how you feed them all and keep the tank water liveable!! that's a lot of babies!

[Haavard Stoere]

Very nice:)

This thread has really fuelled my interest in Pseudacanthicus species. About the species... Maybe it simply don`t have an l-number or name.

[johannes]

any updates?

love your breeding tales, Eltofi!

thanks for sharing..

[ElTofi]

Thank you for the interest...

nothing new about them from March 2009 (last spawning)... Now I can say, with a bit of background, that these fishes seem to be seasonal breeders. I had the 8 spawnings from August 2008, but more regularly between October and March... Every spawning out of this frame was "RO water changes inducted".

I must say that they moved quite a lot... in June 2009 they moved from the 375 liters (last breeding tank) to a 160 liters for their own which they didn't like too much...

I proceeded to a heavy stimulation phase with 50% RO waterchanges during 2 weeks in September and then I let them alone during 3 more weeks... the male made his show with the female, changed 3 times of cave, blocked her during days inside, hurted her on the back and the belly, but nope... the female wasn't ready... So, to avoid a death by multiple wounds, I moved them again this week-end back to the 1600 liters...

Of course, there are more other L-catfishes, of course, there is more place, of course I guess it gives a stop to any breeding tentative from the male... but I didn't want to loose this pair, as it's not so often that you can find a pair of Pseuda who match together...

I will give news as soon as I'll have any... see you.

[Haavard Stoere]

The pictures are not working, and that is a shame because I wanted to see them again.

If the pictures have not been removed from their storage place try editing the posts, and see if there are extra tags. Its sometimes happens with old threads. No idea why.

[ElTofi]

I didn't think about this We changed the server of AquAgora last week and if my picts have been migrated on the new server, the links are broken...

I won't have time to correct this in the next weeks, but I'll take care in November, little by little.

sorry for the disturbance

[Haavard Stoere]

No worries, but I would like to study the pictures some more in the future:)
