Hi,
Although I do not own any nics I do keep and breed Sonoran Desert Dwarf Boas, which are not too dissimilar to nics (i.e. they grow to about the same size, litter sizes are the same and there are naturally occuring morphs).
Right, size first. My adult males are 4ft max and females are 4.5ft. The males are lot more slender than the females (or atleast that is what I have found). The adults females are eating medium/large rats every 10 days and the males are on small medium rats. I have bred mine a number of times with litter sizes ranging from 12 to 17. I have heard of a litter of 26 this year. Like the Nics, the sonoran morphs are relatively new to the market, however, the anerythristic line that originates from my group has proven highly sought after and as a result I have ended up trading for quite a few very nice columbian morphs. The Anerys sell for about the same as the anery nics ($800 to $1000) and are in erlatively constant demand. Therefore, due to the relatively new appearance in the market, I would consider hypo nics to be a very worthwhile morph to invest in. Make sure you acquire the most attractive animals you can and if possible, get unrelated. I am breeding my holdback females from 2002 this coming season so I would imagine Nics would be the same. Good luck and let us know what you decide.
Regards,
Warren Booth
