I fully believe that. I don’t have any experience with sd retics. But underfeeding any snake with intention to keep them small because you don’t want or feel you can’t handle it at full size, is just as bad as power feeding to attain a big snake fast. I always look at it like this. When I got my female green anaconda for example, I researched the maximums in captivity and found, and the average. With that knowledge I assume the largest size mine will likely reach is 18’ and it extremely doubtful she will get that. But, I went into it planning on having an 18’ snake. Anything under is just a bonus that makes it a little easier. I’m not feeding her to grow her faster. I’m not feeding her to grow her slower. I’m feeding her to attain and maintain a healthy life. What’s easier for me should not and will
not trump what’s best/healthier for her.
