The pyros and other smaller kings are hard to start eating and take more specialized brumation.
The Hondurans are a good investment colubrid as they are large ,hardy and colorful. The Vanishing hypos will always hold a higher price. I beleive the amels will go down after 5 yrs and the hypos will remain higher.
I say breed and work with what you like. I prefer the getula as many on this forum do. But IMO they are not as great investment quality snake as the hondurans.
Now as far as colubrids in general. Whew thats a tough one. There are so many asian ratsnakes (coxi ect) coming into the market its hard to tell. The hognoses kinda crashed this year as the high prices people were wanting did not come through.
Then on the lower end of the scale but definetly easier to sell. Are the cornsnakes and calif kings. Kerby (a forum poster) is working with some new calif kings that have perked my interests and they are alos a hardy species.
WSO you have to weigh what is the most important quality to you. Price? Hardiness? Larger market interest?
Narrow it dawn a bit for a better answer otherwise you will just get everyones opinion on what they want to sell and convince you to work with as an investment colubrid.
For instance Terry Dunham might be inclined to tell you snow or Tangerine hybino hondurans, or Kieth might say locality Easterns (LOL), Brandon Osbourn might say Snow brooksi,Dean Alessandri might say Indigos, David Boyle might suggest Ghost brooksi and Kerby will tell you Calif kings.
Now if you really want to see into the future market BUY Hybrids...LOL!
Seriously if you want to make money and that is your goal and you want to do this as an investment get hets. They are boring but they will produce what others have but at a fraction of the cost.
