I see alot of paroons weekly....... i always see some partial short body morphs...... its hard to say at around 4" because they all have bigheads and small bodys but judging form you pic......... it looks like its a partial with the upward arc on the bottom fin.......... The short bodies are quite hard to find. A supplier told me that less than .0000001 develop the short body morph....... then only a fraction of them are going to be "perfect" as far as the spine shape......... def........ a monster fish.........
