Doesn't look like Bujurquina. Species of this genus (the only known representative in Río Meta is B. mariae) have a longituninal band running to the posterior dorsal fin base or upper margin of caudal peduncle, but never towards the caudal spot. I would also rule out that it is Andinoacara cf. pulcher, which would have among other traits a very narrow, inconspicuous caudal spot situeted in the middle of the fin. Cichlasoma orinocense has a very short caudal peduncle and the midlateral spot in a more anterior position, in Aequidens metae the suborbital spot is prolonged to form a vertical stripe along the anterior margin of preopercle, a less prominent fin ornamentation and shorter pectoral fins. Therefore I think your fish are Aequidens tetramerus.The Río Meta representative of this widespread and variable species (or species complex) is - judging from photos of life specimens published in the popular literature - perhaps the most distinctive of the various forms united under that name and may well (i.e. more likely than other forms) represent an undescribed species.
