ID please

Face shape, spangling, broken black line....all indicative of Vieja. Yes, I agree it does look similiar, but don't see any Texas in it.
 
Has anyone noted yet the INCREDIBLE variation among geographical variants in paratheraps/vieja species?!?!
There is absoluteley NO WAY TO TELL THE SPECIES of this fish without counting the fin rays and basically killing it.

Yes, it is a vieja species... but it could be any in the (para)theraps/vieja complex. I have seen hartwegis that look like fenes, syns that look like zonatum zonatum that look like guttulata bifas that look like godmanis that look like melanarus etc. For every species there are countless geographical and colour variants, and given the nature of research in the area the number and variations are not well understood as of this time.

So yes, you have a vieja/paratheraps/theraps species. but there is no way to tell what kind at this point and you will only be able to guess at best when it grows older. Anyone on here claiming to know without a doubt what species it is from that picture alone is just blowing smoke.

If you were able to count the hard/soft rays on each fin and get difinitive numbers you may be able to get a positive id... but this is very difficult.. most type specimens of species are only identified after they have died and are preserved as laboratory specimens
