Synodontis njassae breeding?

[Breezer]

Hi everyone,

I was just wondering if anyone has had any experience in breeding these fellas?

We have some who are currently in with our tropheus duboisi colony and are doing really great. They were only in there as a short term thing until they could be rehomed. Thing is there is this one (i assume girl) who looks ready to pop.

njassae female

I have only done basic research on these fish, enough to make sure they are happy in the tank, well obviously i've achieved that.

So if anyone has any ideas on what these guys do when breeding it will be very helpful.

TIA

looks like gravid indeed

and it's the real thing I think, not one of those unholy bastards

according to literature this species heads for estuaries or surrounding swamps or even goes beyond the deklta's right up to the rivers to breed

to mess around with waterparameters, cool the water (imitate rainy season) looks like the way to go

but i wouldn't do that in a tank housing Tropheus!!

you need at least a few tanks more.

because there's another issue with succesfully breeding any species apart from lucipinnis or multipuncs: you need to separate the sexes for a while. condition them and then introduce the female with 2 males in a spawntank.

wich means you need at least 2 adequate tanks. if you house them too small they get stressed. and stressed Syno's won't breed

that's why Synodontis breeding is such a bother if you prefer the natural methods instead of syringes.

you'd need at least 3 but better 5 tanks or so to breed a single species.
1 tank for the males
1 tank for the females
1 spawning tank with a spawning grid or marbles or any other contraption
1 tank for the eggs or tiny larvae where you can feed with microworms or live artemia nauplii and where you can mess around with acryflavine to prevent eggmould
1 grow out tank for fry that's already swimming and feeding


it takes a good deal of space, money, patience and disciplin e (not to put other fish in all those tanks) to pull this stunt.

I think this is the main reason why so few Syno's have been bred the natural way and I also suspect that the breeders of the granulosus went at it this way and even further: they probably had separate tanks for each adult fish.....separate tanks to house a fully grown granulosus properly (!)
wich means they likely had a big shed with at least 5, 6 or even 8 or more 100G tanks........

You're right Sid! Having visited them & seen the young & adults, each adult is kept separately & they are only brought together for spawining. Whilst being conditioned they are kept apart from each other but in with multis & other tangs with no problems.

As the breeder is part of a commercial wholesaler there is absolutely loads of space. On my visit i was amazed by the range & quantity of species however one of the directors did say they were low on stock as usually they easily have upwards of 1 million fish in stock at any time.

Ok, do you know how to sex these fella's?
I'm new to the syno's and have no idea with them. I have a few (3 x 3ft) tanks cycled that just have some guppies or tropheus fry in them that i can move around (all up i have 28 tanks going). So putting them in their own tanks is not a prob.
Do these guys need hosts like the multi's do?
What kind of substrate do they like best? Out of the 3 tanks that i can use 1 has sand the other 2 gravel.
I'll just syphon out some water from the tanks, and take some from the trophs tank down to the 3fts for the syno's. There are 9 njassae, in with the breeding colony of duboisi.

Sexing is described in the Cat-eLog:

Synodontis njassae

(That, I believe is the same description as any other Syno - they are all the same in that respect).

So true, very hard to do

Do these guys need hosts like the multi's do?

They should not need hosts and I would go with the sand, but also look into marble spawning traps and grids as mentioned.

[Breezer]

Cool, thanks guys.

I'll try and move them today sometime. I'm pretty sure i have another bag or 2 of sand to go in the tanks. So i'll remove the gravel from the other 2 and replace with the sand.
I'll keep you all updated on how we get on.

Thanks.

I was left these fish after looking after them for another person for 2 weeks. I'm going off what i was told. If they are not please tell me.
Was just going to prepare the tanks for them, realised i'm out of sand, so now will have to go buy some or some crushed marble which i can't really get until tomorrow. Looks as though i have another gravid girl. Nowhere near as gravid as the first one, but she's starting to show.

njassae gravid?

Also, i read there are large spot and small spot varieties. I think i have both. There are 2 that have small spots, here's a pic of one of them. Are they njassae small spot?

njassae small spot?

Here's a pic of one of the others that isn't gravid for comparison

njassae

[Birger]

I would just use the large spots for breeding attempts since you have more of them, it would be interesting to see what kind of variation (in spot pattern)there would be in a group of juveniles from a spawn, but that is getting too far ahead, need them to spawn first.
You definitely got lucky getting this group...good luck with them.

Birger

[sidguppy]

it's gettting more and more confusing

see HERE

I looked at my old pictures today; the ones taken after they had a shipment from Stuart Grant himself, back when Mr Grant was still alive and well.

and I'm not so convinced anymore that this is a real njassae

OR

that the njassae is a lot more variable than I think or know.

might very well the case., mind!

in short: I'm stumped......

[Jools]

I think we need full body pictures of all the fish to sort this out!

Jools

[sidguppy]

definitely

good headshots, belly pics, pics with the humeral on it, all the fins, the entire enchilada.


Jools, I still have all the raw originals (they're not many, 5 or so), the uncut uncropped versions of what is in the catelog.

want to have those, so you can edit/crop/cut-out etc for the catelog?

you can cut them into pieces, showing off fins, heads, humerals etc. all in large versions.
these are LARGE files, mind. if I'd printed them we would have posters.

if you like I can send these as we speak.

Sid - the HERE link doesn't seem to work

Further, i wouldn't be surprised if njassae is indeeed a lot more variable than we think, or indeed that like tanganyika, there are some extremely similar undescribed species.

[Breezer]

well seeing as this thread has seen the light of day again, I thought I may as well contribute.

We never ended up with little ones. I'm not sure what happened there, we tried this "2 flower pots one a top the other (yeh I know, hard to keep upright, prop in corner of tank...)in the bottom one put some very large rocks, large enough for eggs to fall through but not big enough for the catties to get down..." but with no success. She'd either layed the eggs and they were eaten, or not sure if they can reabsorb them?

good headshots, belly pics, pics with the humeral on it, all the fins, the entire enchilada.

I no longer have these particular fish in my tank. We handed them on to a friend, so i will try and get there to take some more pics. It would just be nice now to know what they actually are.

I've got a few pics on the computer from when we had them i'll upload a few soon, the only prob is there is the small spots, and large spots. and the mouth shot (not really close though) i have i can't tell which one that is from.
Should i upload the pics on to this thread or the thread in the id section?

[sidguppy]

since we're allup to the eyebrows in determination issues and not in breeding details, I think the ID section would be the most appropriate

Hi, mine Sinodontis njassae very much frequently are spontaneously made multiple copies

Hi, mine Sinodontis njassae very much frequently are spontaneously made multiple copies

Nice one Have you got photos of the parents?

[sidguppy]

I'm quite curious about this too

pics of the parents and how are they bred? artificially? with hormones or naturally?

[oliv67]

I professionally am engaged in cultivation of this fish, basically I plant with the help hormones
Synodontis njassae has at cultivation the certain cycle, then period of rest
Female I have very much and sometimes I simply have not time to work with them, therefore very much frequently cultivation occurs by a natural way
Observed many times very interesting show
Small video of a small part mine Sinodontis

Well,

it is first time I see

Synodontis brichardi

not on a photo . However in this video there is no

Synodontis njassae

.

Next time you are in England (yes, I know, not so easy...), I can tell you where to find some...

[oliv67]

I have a lot of different kinds Sinodontis, on a video basically S. nigrita and S.eupterus ripen after an injection Is and S.njassae

[oliv67]

Has received slightly Synodontis brichardi, very small fruitfulness of a video of good-quality caviar

dunno about you, but apart from the unidentified pic of bab y syno's all the links are spam.......and the text smells like spam to me as well.

all my bogus alerts are going defcon 5, guys.

I'm feeling a little uncomfortable with this too - if the poster is Russian his comprehension of the english language & written posts can easily be excused but are we interpreting what he is saying correctly?

I'd like to see a pic of the njassae parents not the mixed tank of different fish

[worton[pl]]

Hey,

Sid I don't think this is spam.

I am almost sure that Oliv use translator to write so please, be a little bit more understanding since from professional breeder of synos from Russia we all can take a GREAT lesson or if not a lesson a clarification about hybrids .

Every link he posted contains movies of Synos - no spam, really. It is just not easy to find them on the site full of advertisements .

Oliv do you know something about hormone bred plecos or other groups of fish?

Mats - sounds like invitation! . Few members of my family, sadly, have to live and work in England so it is not so hard to make a visit .
In fact after gaining more skills I'm going to try yours highway on my Honda .

Regards.

[oliv67]

Excuse for mine bad English, I really use the program the interpreter
I am not engaged in cultivation Loricaridae, except for three kinds
My work

http://www.practicalfishkeeping.co.uk/p ... ?news=1633

Also some other families of catfishes, also Mastacembelidae and other interesting kinds
The basic direction Sinodontis, including there are a lot of new interesting hybrids, I have very much wide experience
