If your tank is small and you do not provide a hiding place... there will be aggression with plecos...
Also.. if you have opposite sex.. it will be fine....
As for L47, and L14.. since the two species' diets are different I would avoid it if possible..meat eaters and Veggie eaters dont mix very well... it can lead to aggression from plecos.. as meat eaters have sharper teeth compare to veggie eaters..
I would avoid it.. its possible to keep them together... but.. best to avoid..
