OK, so from what I've gathered there are a couple distinct morphs of vents. there are the peruvians (yellow belly), and the morph from french guiana (yellow chin and blue belly). Now, of these which are the most common within the hobby in the US. I've also heard of a Kelley line of vents, and was wondering which morph this line represented. Thanks for the help, and be sure to let me know if I have some bad information here.
