Restricted to the rainforests of the Poroto Mountains of Tanzania, C. fuelleborni reaches a length of only 8 inches with exceptional males to 10 inches. They are moderately aggressive toward conspecifics and timid toward keepers.

C. fuelleborni is generally similar to C. jacksonii but smaller and plumper in appearance. This species is easily confused with C. werneri. They may be distinguished partly on the basis of the occipital lobes. The occipital lobes of C. fuelleborni have a maximum of 15 large, plate-like scales covering each lobe. These are intermingled with smaller scales. C. werneri has up 30 such plate-like scales, giving the impression that the lobes are larger and more elongated than in C. fuelleborni. Thus, the lobe scales on C. werneri appear to be finer than those on C. fuelleborni (Rob Pilley, personal communication). Male C. fuelleborni exhibit 3 well developed, annulated horns (2 preocular and one rostral) that are markedly smaller than C. jacksonii. Females possess 3 small, annulated horns. There is a prominent occipital lobe. The anterior segment of the parietal crest is forked. Ventral and gular crests are present as is a prominent dorsal crest composed of unequal sized cones. Squamation is heterogeneous. Coloration is a medium to light green with brown patterning. Scales on the occipital lobes, eye turrets and at the base of the horns are often a brownish-red. Off-white, broken stripes run down the flanks.

The preocular and rostral horns are markedly larger in males than in females and this difference becomes apparent at approximately 4 months of age. Sexual maturity is achieved at approximately 6 months of age. Four-15 live young are born in a single clutch. It is typical to have only a single clutch per year.
