who am i ?

elongatus

[Kenneth]

a cool lookin fish that i wish i had in my tank... lol

[AlvinV]

I had one of those, just can't pin the name right now. Just so that we're on the same page - would that be among the most aggressive fish in your tank if all the fish in your tank were the same or similar size? Have to see the "jaws" more clearly just to make sure.

[SGypsyMermaid]

looks a lot like my trophehops "higga reef".

[SCOTTIE-ROX]

AlvinV it is the most aggresive fish in the tank, I have 2 others that are the same species. I have some other frontal shots at home I can post later.

SGypsy I am fairly sure it is in the genus psudotropheus, but I am not sure of its origin, because there are so many within the elongatus variety.

[Seedy]

Could it be a local variation of a P. demasoni? Frontal pics of the jaws/teeth would help...orange egg spots...hmmm....

[Melsker]

Could it be this????

The dark stripes do not go all the way back to the tail on the fish in the link and your fish has more of the dark color in it as opposed to the light color so its probably not yours but it does have the yellowish egg spots?????

Otherwise I was thinking P. Demasoni?!?!

[Seedy]

The biggest difference between a C. afra species (what melsker pointed out at malawi mayhem.com) and a P.demasoni is in the teeth, P.demasoni has bicuspid teeth and C.afra's have unicuspid teeth...lets see a jaw pic!

:ok:

bicuspid 2 teeth, unicuspid 1 tooth:confused:

[Seedy]

Ok, so the tooth issue is actually a finer point of their physiology but it helps to show how they have evolved to every feeding niche of the lake...

Here is a good article

if I would have to take a guess based on the first pic, i would say a male P. saulosi (i have seen pics of males with 7-8 bars..others with less)

[SCOTTIE-ROX]

looks more like the Cynotilapia afra "Lumbila" pic from your site. How do you tell the difference between cynotilapia and psudotropeous jaw?

[Seedy]

Cynotilapia - Regan, 1922

Representatives of this genus have long, well-separated, unicuspid teeth, strongly conical in the outer row. The teeth of the inner rows are smaller and irregularly spaced. In the aquarium, as in the lake, male are highly territorial. Housing them with other mbuna in a well-populeted aquarium will minimise the effect on individual subordinate fishes. Females and juveniles form schools in open water in the lake.



Pseudotropheus - Regan, 1922

This genus cannot be clearly differentiated from other genera on the basis of dentition. Instead the position of the lower jaw (when the mouth is shut) is more iportant as regards morphological differentiation. In this genus the lower jaw runs parallel to an immaginary line whose end points are the tip of the snout and a group of bones in the caudal peduncle. Pseudotropheus are regarded as less aggressive than other mbuna, although males are highly territorial among themselves.

What do i need for a definative id? I could catch this fish and get up close shots of his head and jaw line.

ahhh, yes...but having good researching skills has merit. knowing what to look for and where to find it is almost as good as writing it yourself!:D

[SCOTTIE-ROX]

:uh: :hmm: :uh:

:drink: I don't get it?

But seriously I still can't tell :confused:

New pics of the two others that are the same species will be up in a new poll as soon as my new tank clears up.
I also have some questions about that in the african tank forum.:ok:
