Geo Sp Red Head Tapajos Or Not?

[kaivalagi]

Hi All,

I have a question regarding one of my geos. I thought after some growth I'd post comparison pics between equally sized tapajos and the "might be" tapajos fish. The 2 fish compared were bought at the same time from the same LFS tank, at the start of May this year.

These first 2 pics are the suspected non tapajos geo':

An these 2 pics are of definite tapajos variety of geo I have (closest matching size to the above)

Could it be that the first fish pictured is infected? I find it hard to believe though as the fish has too many differences e.g. more red colouration of fins, lack of full fin patterning, pelvic fin has no whitening, eye colour differs too. It is the slowest growing of the group and doesn't mix with them all that well...but seems healthy and eats as well as the rest which is greedily

If not a tapajos then what do you think the first pictured geo is?

Your advice and comments would be very gratefully received

Cheers

The top two fish aren't orange head Tapajos IMO. My Tapajos, even at a small size, show the striping in the fins.

I am pretty sure the first fish pictured isn't a tapajos either, any idea what it might be?

looks like surinemensis!

Hi RDP, fancy seeing you here too

I see where you are coming from...the more greener and uniformed colouration. But it is growing so much slower than the tapajos that it was bought with and considering a surinamensis gets to a greater size it sort of contradicts things a little...

Even so I am with you on the id so far though, I've been looking though as many profile pics as I can find and it certainly matches the Surinamensis the best so far.

Time will tell I suppose, it's just going to be a long wait

Thanks

First fish looks like G. abalios. Remember that G. surinamensis essentially don't exist in the hobby, it's just a slushpit name used by wholesalers. Can't give a definite ID, looks like a small black pre-opercular mark coming through as well.

Second fish is definitely a Geophagus sp. "Orange Head".

Something else I didn't realise, they're hard enough to id when young but having false species names added to the mix doesn't help

Could the slow growth of the potential "Abalios" be down to not being with any of it's own kind? And therefore no competition as it were for seniority?

I pop up all over the place! LOL.

Geophagus Winemilleri maybe, see this:
