Thoracochromis demeusii???

Post by Mark Smith » Thu Apr 12, 2007 3:58 pm

I just recieved this cichlid from Rehoboth Aquatics recently, and I think it may be Thoracochromis demeusii. It is a male.

Any thoughts from anyone out their??

I ordered some "Ctenochromis polli" from Toyin, and I got Thoracochromis demeusii. I would have been happy to get the polli, but I was ecstatic to get the demeusii! :lol:

I understand. It is a unique and unusual cichlid from West Africa for sure.

I took this picture a long time ago.
Anton Lamboj ID it as T. demeusii and included it in his book

How long was that specimen you photographed? It looks like a sub-adult or female??

No. I ordered C. polli and got C. polli. Toyin mentioned something else that came in with them, but he was not absolutely sure as to what they were. I bought them to see what they would be, and it seems like they are T. demeusii.

Mark,

speaking of T. demeusii, a while ago I browsed the web trying to find out if someone was keeping T. callichromus from the Fwa River, and was lead to Ted Judy´s site, with photos of a supossed T. callichromus:

I'm quite certain this fish is not T. callichromus, my initial thought was T. demeusii, and it does resemble your fish a lot. Any thoughts on this?

All the best, Thomas

I think you are right , Thomas. This fellows fish is definitely not a Lake Fwa fish.

It would be great to see someone working with the actual C. callichromus. I remember starting a thread on this cichlid and C. brauschi, and cannot remember at the moment if anyone is actually working with C. callichromus presently.

THank you for the correction. So few Thoracochromis are seen here in the states that it is hard to get much experience with ID. Just for my own clarification, is the fish on my website demeusii? Also, what is it about the appearance of the fish in the pictures that indicates "This fellows fish is definitely not a Lake Fwa fish"?

Hi Ted

Good question. The best thing to do is to become familiar with the 5 species of cichlids that are edemic to Lake Fwa. It will then become more clear in their differentiation from the few Thoracochromis species that trickle into the hobby. The Lake Fwa cichlids seem to form 3 natural groupings. One group consists of T. brauschi and T.callichromus, the other of Schwetzochromis neodon, and the last group of Cyclopharynx fwae and C. schwetzi.

A great paper appeared on these fish in Ichthyological Explorations of Freshwaters in 1994 in volume 5, number 2, pages 97 to 154, by Roberts and Kullander.

It looks more like T. demeusii to me, as the photos do not show any red on the breast, and the female has a "bug-eyed" appearance, something that I'm not sure C. polli females look like. The photos are not at a complete side view, so it makes it hard to be 100% sure, though.

I'm starting to think that I really did get the Ctenochromis polli. The males that I have do have a red throat. Also, the nuchal hump on the males is not even close to being as pronounced as in the photo posted all the way at the top.

This is getting very confusing for me! The fish that came in as polli I thought were demeusii, but really are polli. I also got some fry from a friend of Sam Borstein's that were supposed to be Thoracochromis callichromis, but are likely demeusii. :lol:

I guess all I really need now are some of the real callichromis.

Now I'm confused too :lol:

Mark, do you have a photo of your C. polli for comparision?

All the best, Thomas

Once you see both species side by side, it is quite easy to tell them apart. It sort of reminds me of the difficulty I used to have in differentiating Xenotilapia sima from X. boulengeri, similar species, but easy to tell apart when you see them side by side.

Sorry to dig this up... haven't been online very regularly in a while.

T. demeussi have been in the hobby off and on under a variety of names, IMO. Pics below are F1 from wild fish imported by Toyin in 2006 as "mystery cichlid from the Congo". Easy to keep and breed, if you can keep the males from killing each other.

C. polli is, IMO, a very different fish. I have images somewhere of fish I picked up as contaminants in a shipment of S. casuarius from Nigeria. Hard to miss the red to black throat on males of this species.

Ted, is your fish from Jeff Michaels? I received juveniles of "Thoracochromis callichromus" from him that looked very different from my T. demeussi juveniles.

edit: why are images being chopped off? Is it just me?
