its something old-school asian aro keepers really look for. though this depends on individual preference, basically yes....it is a sought after trait. this trait is mostly applied with selections for super red arowanas especially the chilli reds, and even with rtg's. though it sometimes appear in x-backs also, but with regards to this variety bullet heads are considered more desirable. as a testament to the importance of this trait, arowanas which exhibit severe spoonheads (even looking like a hunch-back specimen) are given the title "king arowana". this trait normally does not occur with the south american aros (silver and black), but mild spoonheads are also sometimes shown by the australian aros (jardinis and leichardtis).
