Despite spending a lot of my day reading up on pike cichlids I'm still having trouble distinguishing which species stay medium-sized (6"-9" max) and which get much larger (15"+).

I'm looking for one that won't get larger than 6-10" for a 150 gallon aggressive tank. Any input?
 
if you can find crenicichla sveni, they're really active & I've kept them with aggressive cichlids & other (gar, pacu, & clown knife) they fended well & have good coloration
 
the one with its mouth open when you google image search "crenecichla sveni" was mine
