You can't get like me
Is the 14 gallon the hexagonal tank? You could make one out of wood, and stain it.
The cichlids I mentioned would be more peaceful than Kribs IMO but also I think 15g is a bit small for kribs.
Any of the dwarf cichlids I mentioned would work really nice with some pygmy cories. As for small plecs just go for bulldog plecs L187 quite cheap and common but avoid any other type of common plec even bristlenoses will get too big for that tank IMO. You could even do a small school as well.
Maybe something like
2 Redbreasted Acara (1m 1f)
6 Rummy nose tetras
6 Pygmy corys
1 Bulldog Plec
