Hello,
First pic is of the T. macrostoma. Last shot is i believe is the T. nigriventer. Those are some really awesome fish. As for sexing I can't help. How big are they? Its good to see someone with some great large predators. When they mature they are sure to be beautiful. Good luck with those guys and congrats on picking up some really awesome fish.

ok bro!!! thank you..I wanted to make sure..that what the seller told me..I also got the maculips.not sure if the spelling is right. marcos is 6-7inches, 6inches for nigriventer, and 5inches for the maculips.
again thanks for the comments
 
Shouldnt the Macrostoma be darker?

They got their nickname as blackbellie as the females can be completely black on the stomach region.

You mean the Maculiceps, the last and 2nd picture appear to be Nigriventers.

(Have a look on my site, I have some photo's there of my tyrannochromis species as well. I am still searching fro Macrostoma's and Polyodons)
 
here are a litttle better pics

The lighter color could also come from the lighter colored gravel, but when they mature, gravel color probally won't matter.
 
Per your PM-The one with the broken bands is definitely T. nigriventer (probably male given the blue lips).

The one with no markings is T. macrostoma (still sold as T. maculiceps in some places).

According to Ad Konings (pers. comm. in the mid 90's over a few beers after a presentation) T. maculiceps is not a valid name anymore. The fish that was known as T. maculiceps (adult male color is light blue with yellow belly) is really T. macrostoma. The fish that was T. macrostoma is really T. nigriventer (the fish that looks similar to a fusco when colored). I still see all three on lists--including lists from Old World, so Im not sure what the deal is. T. sp. Orange Spot is T. nigriventer 'Tanzania' (FYI)

Hope that helps a bit. As for your T. macrostoma--Ive never seen one without any markings whatsoever-typically they have a couple horiz. bars and a darker tan belly when uncolored.
