I've done some research about the article describing coloratus, and apparently Dr. Takashi believes that this especies is present in the hobby as Jumbo Cyp, C. sp "GoldFin". I've tring to find Goldfins, either in local fish store ou on Web sites, because all the pictures I've found look different from the pictures included in the description.

Has anyone been able to confirm this, or keeps coloratus? If someone has GoldFin or coloratus, please post some pics.

Another thing is the mention to the breeding sincronism with the lunar cicle. I'm from APC (Portuguese Cichlid Association) and I spoke in our convention about the coloratus, and I asked the audience if anyone had moonlight simulating devices with Cyp leptosoma. One attendant has his tank near a window, so it receives light from the moon as well, and he never noticed any kind sincronism. So I expeculated if it could not be that the sincronism is not with the moon, but with Lepidolamprogus attenuatus or L. profundicula spawning so cyp fry can benefit from their territory/fry protection, and that are Lepidolamprologus that sincronized with the moon?

What do think of this? Has anyone been able to experience this sincronism in the aquarium? Might it be that only when threathened, will the cyps sinchronize their spawns?

Best regards

Interesting question Ricardo. I bet most fish keepers don't keep track of spawn dates with regards to the timing of the lunar cycle. It would make an interesting study.

[Philippe Burnel]

I have done this study a long time ago.
It', in my point of view, impossible to have real conclusions.

[Ricardo Sousa]

Could you tell us how you did the study, and what results did you get, even if they weren't conclusive?

Did you experimented with Lepidolamprologus present in the same tank, or was it just the moonligth?

I would really like to hear about your study.

[Philippe Burnel]

I have experimented with many lamprologine sp and mouthbrooders (Malawi and Tanganyika) during about 3 years.
There is no real result that can be helpfull.
Infortunatly, this is very old (at least 10 years) and, as there was nothing really interesting, I didn't keep the results.
There was indeed a little difference beetwen substrat spawners and mouthbrooders.
Substrat spawners tend to spawn around the "pleine lune" (how do you call it in english, when the moon is completly lighning) and the mouthbrooder during the "nouvelle lune". So my conclusion was that the fry was free swimming, in each case, when the light of the moon was at its maximum (even if the tank was in a fishroom without light coming from outside).

(Expecting this is understandable !)

"pleine lune" would be full moon (all the moon visible), and the nouvelle lune is new moon (you don't see the moon).

Ricardo,

I think it was Ad Konings who first recognized the Goldfin as an undescribed species. It occurs sympatrically with C. sp. "leptosoma jumbo". You can read about the Goldfin in Ad´s article "New Cyprichromis from Zambia" in Cichlid News (Oct. 2003 I think) or get it right here (it's well worth the 2 dollars ) : http://www.cichlidae.info/article.php?id=348

Here is one of Ad's pics of a C. sp. "leptosoma goldfin" aka C. coloratus



All the best, Thomas

Hi Thomas,

Thank you for the info, but I already knew that picture, it's probably the most know picture of goldfin on the net, and that's exactly my problem. When try to compare that picture with the ones Dr. Takashi used in the species description, something is not right, in my eyes at least.

Ad's female picture seems to me, as being identical to the one in the description, but not the male. In Ad's picture, the last part of the dorsal is more rounded instead of pointed, and it has a blue rim not visible in the two male pictures of the article. The caudal is electric (fluorescent) blue, the same color of the dorsal rim, which isn't present in the description or photos.

This diferences makes me think that GoldFin might or not be a coloratus, and if it is, it might be a variation of the ones described.

What do you think of this?

[Thomas Andersen]

Yes, I can see what you mean

In the Cichlid News article there is a photo of C. sp. "leptosoma goldfin" male that has a bit more pointed edge to the dorsal than the photo I posted. Ad lists Isanga Bay, Chituta and Mbita Island (another name for Nkumbula Island, collection place of some of the type specimens of C. coleratus) as localities where he found the Goldfin. I think Ad's pictures are taken in Isanga Bay, so a differences in coloration is possible. Also the colors of the preserved specimens may have changed a bit during preservation.

So, I think the Goldfin is the C. coleratus

All the best, Thomas

Ricardo,

here's some pictures of a Cyprichromis sp. "leptosoma goldfin" from Mbita Island that were imported 1½ year ago:

Hi,

Those Cyps in the pics, in fact resemble the pictures in the description, and I have no problem in seeing C. coloratus in them. But these don't have any colored edge (rim) on the dorsal and anal fin.

Beautifull fish and pics by the way. Thanks for sharing.
