Ive pretty much have had the same issues with cb polys. My cb teugelsi will eat way too much and looks like it has a beer gut. Same issues with cb sen and a bit with a cb del. The 'full' mechanism just does not seem to operate right. My wc will eat and when they are done they stop.This is the problem with cb species, ive noticed this with my ornates and cb endlis, they just dont know how to stop when it comes to eating.
