It's not a Geophagus surinamensis, you could get that answer from any number of inexperienced keepers. Lateral spot is a bit large for an altifrons variant, even at that size in my experience.

Has quite a sizeable dorsal fin from those photographs, but I'm not sure whether what looks to be a pre-opercular mark is actually one, but I'm with peathenster on this one, looks like a sub-adult/juvenile G. winemilleri. Eye colouration, fin patterning, barring and lateral spot size and position all fit.

Thanks heaps for that.
Would you say that the fish look OK for their size?

hopefully one is a male, than it can possibly breed with Phenomena's lonely 4 female winemilleri

I've just realised you're from Australia, in Sydney/Melbourne as well I would presume. As mu_2176 above me has mentioned, winemilleri are as rare as hens teeth over here.

Hard to tell from your photos due to the subtle colouration of the lateral spot, but I've been told (and agree) that these fish are Geophagus sp. "Rio Branco".

UPDATE:

Here a few updated pictures to give you guy's an idea of how my Rio Branco are going.
It appears that I have got 3 males and 2 females.

From this in July:

To this, taken today:

Sorry in advance about the quality of the photo's.

Cheers

Looking good, definitely Geophagus sp. "Rio Branco", can see the large extended lateral spot a bit more clearly.

wait...why is this not G. brachybranchus?
