Suprised only one Caquetaia! Parachromis only for dovii so for me it wouldnt be a whole genus.
Caquetaia would be first because they are full of color and are challanging in terms of sex, Umbee you have a long time of watching it in its different stages. Dont have any other Caquetaia but have been researching and the rest are for sure on my list.
Second would be ex cichlasoma dont know if thats a genus. Just look damn cool.
