Surinames are awesome but they are more demanding on feeding and husbandry. I use T8s for babies and juveniles but for an adult, i would do nothing smaller than a T25.
Also realize they arent cheap unless you are buying a flesh peddler one like LLL or Underground reptiles. If you are buying from a reputable breeder, be ready to drop $500+.
Feed conservatively and stay on the smaller side. My female Rio Bravo Poki suriname is 1.2 years old and she just graduated to small mice every 2 weeks.
And here she is being her lounging self lol.
And a more recent pic of her after shedding.
Good luck on the hunt. Took me awhile to find the perfect one with the blood line I wanted. Now to find that perfect Peruvian BCC.
