Thanks everybody for chiming in. Some of the selection for favorites surprises me considering there are more rare plecos on the board. Proves the point in it's not how rare it is but just preference in appearance. Here are the selected count so far, some of you picked more than one but how can you not? lol. I still counted them:
BEC: 1
XANTOS: 2
GOLDIE L14: 3
GOLDLINE L27: 0
XINGU L27: 0
MANGO L47: 1
DRAGONFIN L91: 3
GOLDNUGGET L177: 0
TYPHOON: 2
LEOPARD CACT: 0
TITANICUS: 3
So far it's between Goldie, DragonFin, and Titanicus.
