Sexual dimorphism on Triglachromis otostigma

[Changongo]

Hi all,
here a visual approach to understand sexual dimorfism on the mud-dweller cichlid Triglachromis otostigma. Pictures belongs to a extensive photographic report about its reproductive strategy.
Despite, some mating behaviour have been observed, the breeding is still waiting.
Doubtless, one of my favourite cichlid.



All the best

Nice pics, there are too familiar for me. I think maybe i saw before.
Please, can you show a xeno genital pore image or a web where we can see the diferences?

[Changongo]

Hi Sergio,
you can check the picture you request at Konings book "Back to nature, Tanganyika Cichlids" 2nd edition.
By the moment I prefer to not practice "the sexologist play" with my sensitive Xenotilapia.
However the papillae type of Xenotilapia is more similar to that of Triglachromis type than the ones of other genuses (i.e. Tropheus spp. ) so I think the picture shown can be helpful for you.

Best

Angel, thanks for posting your photo, it's very informative.

By the way, what happend to your pics in this thread? http://www.cichlidae.info/phpBB2/viewto ... ight=#8247

Your pics of Reganochromis calliurus and Triglachromis otostigma were stunning!

All the best, Thomas

Ok Angel, thanks i try to do. I know that tropheus are not too similiar to xenos.
I think it can help me, thanks another time.

Hi,

I find some reproduction pics on a sweden forum, but I don't understand nothing... It may be very interesting

Too bad Babelfish doesn't do Swedish to English, otherwise it'd be dead easy.

FWIW male Triglachromis have black spines up front in the dorsal, females lack these or they're only hinted at.
but it's very hard to see when having just one fish. if you can watch a group it's much easier.

This can only be used with (almost) fully grown adult fish; young Trigs ALL have dark spines in the dorsal, or the differences are too random to spot.

females have a bigger, deeper body and usually it's a bit more pale; the length of the male and female fish is equal. This too is only obvious if you can see a group of (sub)adults.

At last!!. After almost 18 months my Trigs have spawned.


Male


Female

Note clrearly diferent dorsal fin pattern.

Female guarding eggs

Both fishes are exchanging eggs every 2-3 hours.

Very cool! Keep us updated on the progress of any fry.

Might this be the first ever recorded spawning of this species in captivity?

[Changongo]

No Mark,
for sure is not the first, but probably one of the few. Be sure I will try to illustrate it as best as I can for the future. I am carefully recording lots of data for an eventual report.

Best,
Angel

[Mark Smith]

Good to know. Now if someone could just spawn the blue variant of Neolamprologus sexfasciatus and document it with photos!

Congrats Angel.
Stunning pics once again

[Changongo]

Thanks folks,

[Thomas Andersen]

Angel, you've done it again - amazing photos!! Congrats on the spawn, it will be exciting following how things progress

All the best, Thomas

Hello,

Nice pics

Could you discribe us your tank, and the installaion for exemple the luminosity of the tank, and if you put some PVC pipes ..

Thanks, and good luck...

[Lisachromis]

Wow! What a shot. Just makes me jealous to see them.

[Ammavita]

Excellent Angel, congrats with the spawn and good luck for the next steep.
By the way, very nice pics as usual...

Parents are still working together, but now they guard something diferent than eggs









This is the simple scenery where things are happening. A 96 liter tank, 20 l of beach sand and a couple of PVC pipes.
Subdued light atmosphere and slow moving water are part of the keys.

Best,
Angel
