True geo redhead tapajos

Hey Ed,

Myself and another enthusiast are curious as to why you don't believe the fish pictured in post #25 are not an altifrons variant.

He's pointed out the following to me: They have a spotted caudal fin quite different to G. abalios (even young fish). Eye colour is not overly different to altifrons i.e. slightly red. G. altifrons do get split lateral barring too.

We're mainly curious because there is a species going around in Australia with sub-adults that feature a very similar head-shape which is quite pointed and steep, exactly like what peathenster has posted. They end up looking like these guys, http://eartheaters.qldaf.com/index.php?page=altifronstocantins2, which we have labelled as a variant of altifrons "Tocantins" as they were labelled as this when sold, but have quite a different bodyshape - and we're trying to distinguish what they really are, as we're quite sure they're not a Tocantins.

Cheers,
japes.

Hi japes,

Since that post we did determine that the fish in post #25 was not G. abalios. I made the comment about not being an altifrons variant because of the last picture where the abodminal spot looks quite large. If you click on the second image you can (semi-accurately) count the scales within the the spot. It covers at least four scales which would be the maximum for an altifrons. The last image looks more remininscent of a regular-sized abdominal spot, but it is not being positively expressed. I'm sure peanthenster can post more pictures after the fish has put on some weight and matured a bit, I'd like to take another look. The images you linked do look to be some sort of altifrons-type species, but I agree they looks somewhat different than the more common variants. peanthenster's fish came in with fish from the Rio Tapajos, so maybe it is indeed from there, but the fish in the link do not really match that variant either. I don't think I've seen a fish exactly like that in the states. But for peanthensters fish, it probably will prove to be an altifrons, I was just a little unsure about the spot in the last photo.

Just took a few new pics. Sorry for the quality - it's very guarded tonight and only stays in the back of the tank.

It has been named Geophagus sp. peter until you guys figure it out

Hey Peter,

I believe I was wrong initially. The new pictures do look like an altifrons. I would like to see an update in a few more months though.

Then it must be the plainest altifrons of all time....at least for now...will update...

Going to bump this thread.

Here's what me and a couple of others believe your little plain altifrons may grow up into.

Any photo updates?

yeh id say those are very similar, they are getting the yellowish colour underneath too.

 

[peathenster]

wow...I sure hope so! Seems like "Tapajos" does have more yellow on the under side.

Not there yet but starting to show some color .
