The Disciplines

Eight fields. One craft.

Every discipline is a complete department of study. Open any one to see its courses, levels, and what you walk away able to do.

Everything else fails without this. Husbandry is the discipline of building a captive environment an animal can thrive in for decades — not survive in for a season. You learn to think in gradients and systems, to read an enclosure the way a vet reads a chart, and to fix a failing room before the animal tells you it's failing.

Courses
  • HUS 101

    Foundations of Captive Environments

    Foundation6h

    Thermal gradients, photoperiod, humidity, and the closed-system mindset every keeper needs first.

  • HUS 210

    Bioactive Vivarium Design

    Intermediate8h

    Living substrates, clean-up crews, drainage layers, and the biology that keeps a tank stable for years.

  • HUS 245

    Thermoregulation & Lighting Science

    Intermediate6h

    UVI, basking physics, ferguson zones, and building gradients that match the wild template.

  • HUS 320

    Rack Systems & Collection-Scale Husbandry

    Advanced7h

    Keeping dozens to hundreds of animals correctly — airflow, hygiene, and never losing the individual.

  • HUS 360

    Water, Air & Microclimate

    Mastery6h

    The invisible variables: humidity cycling, ventilation, and the microclimates inside a single enclosure.

What you'll be able to do
Build a stable thermal gradient from first principlesDesign a self-sustaining bioactive vivariumKeep at collection scale without losing the individualDiagnose an environment before it costs you an animal

The science the hobby usually fakes. You learn how inheritance actually works in reptiles, how to do morph math without a calculator, and how to design a multi-year breeding project that arrives where you said it would.

Courses
  • GEN 110

    Principles of Reptile Inheritance

    Foundation6h

    Dominant, recessive, co-dom, incomplete dom — and what each really means at the cellular level.

  • GEN 215

    Morph Math & Punnett Fluency

    Intermediate6h

    Calculate the odds of any pairing in your head, including multi-gene combos.

  • GEN 280

    Line Breeding & Project Design

    Advanced8h

    Plan a project across generations — selection pressure, record-keeping, and the long game.

  • GEN 360

    Polygenics, Combos & the Limits of Selection

    Mastery6h

    Where simple Mendelian rules break down, and how master breeders work past them.

What you'll be able to do
Solve het and combo math on sightDesign a multi-generation morph projectKnow the limits of selection

Reproduction is the proof a keeper truly understands an animal. You learn to condition, cycle, pair, read a gravid female, incubate correctly, and bring neonates through the most dangerous weeks of their lives.

Courses
  • REP 130

    Reproductive Cycles & Conditioning

    Foundation6h

    Seasonality, body condition, and getting animals ready to breed without burning them out.

  • REP 220

    Pairing, Ovulation & Follicle Reading

    Intermediate7h

    Introductions, lock behavior, and reading a female by sight and palpation.

  • REP 290

    Incubation Science

    Advanced7h

    Temperature, humidity, substrate, and temperature-dependent outcomes done right.

  • REP 310

    Neonate Care & First Feeds

    Advanced6h

    The fragile window — first sheds, first meals, and starting problem feeders.

  • REP 350

    Reproductive Failure & Problem Pairings

    Mastery6h

    Slugs, retained follicles, egg-binding, and the hard diagnostics when a season goes wrong.

What you'll be able to do
Condition and cycle a breeding pairRead ovulation and follicle developmentIncubate to a target outcome

Taught for understanding and safety first — never as encouragement. This track covers the protocols, equipment, and discipline that keep advanced and venomous keepers alive, and the medical reality of what happens when the rules are broken.

Courses
  • VEN 200

    Protocols of Hot Keeping

    Intermediate8h

    Locks, hooks, tubes, two-person rules, and the discipline that makes safety automatic.

  • VEN 310

    Envenomation, Antivenom & Emergency Response

    What venom does, what antivenom can and can't do, and the plan you build before you ever need it.

  • VEN 380

    Advanced Handling Theory

    Mastery6h

    The mechanics of safe restraint and movement — taught to remove mystery, not to invite risk.

  • VEN 420

    Building a Venomous Collection Responsibly

    Mastery6h

    Permits, caging standards, room design, and the ethics of keeping dangerous animals.

What you'll be able to do
Understand hot-keeping protocol and equipmentKnow the medical reality of envenomationBuild an advanced collection responsibly

Most reptiles hide illness until it's nearly fatal. This discipline teaches you to see it early — quarantine and biosecurity, parasitology, the subtle signs of disease, and what to do (and when to refer) in an emergency.

Courses
  • VET 120

    Quarantine & Biosecurity

    Foundation6h

    The single highest-leverage habit in the hobby — done the way a real facility does it.

  • VET 210

    Parasitology & Fecal Diagnostics

    Intermediate7h

    Mites, worms, protozoa, and reading a fecal — what you can do at home and what you can't.

  • VET 260

    Reading the Sick Animal

    Intermediate6h

    Respiratory infections, stomatitis, neuro signs — the early tells most keepers miss.

  • VET 340

    Emergency & Critical Care

    Advanced7h

    Burns, prolapses, dystocia, trauma — stabilize, decide, and know when to refer.

  • VET 380

    Working With Your Vet

    Advanced5h

    Diagnostics, imaging, surgery, and building a relationship with a real reptile vet.

What you'll be able to do
Run a real quarantine and biosecurity protocolIdentify common parasites and pathogensRecognize a sick animal early — and act

Feeding is where so many collections quietly go wrong — too much, too little, the wrong prey, the wrong supplement schedule. You learn to feed for a long, healthy life, and to solve the feeding problems that defeat most keepers.

Courses
  • NUT 115

    Prey, Nutrition & Supplementation

    Foundation5h

    Whole prey, gut-loading, calcium and D3, and building a schedule that actually balances.

  • NUT 205

    Feeding Response & Problem Feeders

    Intermediate6h

    Scenting, assist vs. force, and the patient methods that start a stubborn animal.

  • NUT 250

    Obesity, MBD & Metabolic Balance

    Intermediate6h

    The slow diseases of overfeeding and poor lighting — how to spot and reverse them.

  • NUT 310

    Feeding the Difficult Species

    Advanced5h

    Specialists, seasonal fasters, and the species the care sheets get wrong.

What you'll be able to do
Build a species-correct feeding planFix a problem feederPrevent obesity and metabolic disease

Captive husbandry is only as good as the wild biology it's modeled on. This discipline takes you into natural history, responsible fieldcraft, and the keeper's real role in conservation — without the romance and without the harm.

Courses
  • FLD 140

    Natural History & The Wild Template

    Foundation6h

    Where the animals live, how they live, and how to reverse-engineer captive care from it.

  • FLD 230

    Fieldcraft & Responsible Herping

    Intermediate6h

    Finding, observing, and documenting wild reptiles without disturbing them or the law.

  • FLD 300

    Conservation, Ethics & the Keeper's Role

    Advanced6h

    Trade, locality, assurance colonies, and how private keepers genuinely help — or hurt.

  • FLD 340

    Locality, Provenance & the Wild Bloodline

    Advanced5h

    Why where an animal came from matters, and how to keep and track locality data.

What you'll be able to do
Model husbandry on real natural historyHerp the field responsibly and legallyUnderstand the keeper's role in conservation

The discipline almost nobody teaches. Turning serious keeping into a sustainable operation means records and pedigrees, the ethics and economics of breeding, shipping live animals legally and humanely, and building a name that outlasts any single season. This is how a hobby becomes a legacy.

Courses
  • BIZ 150

    Records, Pedigrees & Husbandry at Scale

    Foundation5h

    The systems that let you track hundreds of animals, lineages, and outcomes without chaos.

  • BIZ 240

    Ethical Economics of Breeding

    Intermediate6h

    Pricing, supply, and producing animals the market and the welfare standard both respect.

  • BIZ 310

    Shipping, Welfare & the Law

    Advanced5h

    Live-animal logistics, permits, and the legal landscape every breeder has to know.

  • BIZ 360

    Brand, Reputation & the Long Game

    Mastery5h

    How the names that last got that way — trust, consistency, and decades of doing it right.

What you'll be able to do
Run records and pedigrees like a facilityPrice and breed ethically and sustainablyShip live animals legally and humanelyBuild a reputation that compounds

The Credentials

A credential ladder the reptile world has never had.

Four tiers, each one earned. From your first proof of competence to a permanent seat in the Citadel. Open any credential for what it takes and what it grants.

  1. I

    The foundation credential and the front door of the Citadel. It certifies that you can run a correct environment, feed for health, maintain real biosecurity, and understand the wild biology behind it all. Earn it once and you carry it for life.

    What it grants
    • The CCK post-nominal
    • Citadel Keeper standing
    • Entry to Culebra Connect community
    Prerequisite

    Open to everyone. No prior credential required.

  2. II

    Go deep instead of wide. The Specialist credential certifies advanced command of a single discipline — genetics, reproduction, veterinary, venomous, or any other — assessed by a portfolio of real work and an oral review with faculty who do it for a living.

    Requirements

    Two Specialist credentials.

  4. IV

    Not earned by coursework — recognized. Fellowship is the Citadel's highest honor, granted by nomination and full Council review to keepers whose life's work has moved the entire craft forward. A Fellow holds a permanent seat and a voice in the curriculum itself.

    Requirements
    • Hold the Master Keeper (CMK) credential
    • A sustained, recognized contribution to the craft
    • Nomination by two Fellows and full Council review
    What it grants
    • The FC post-nominal, for life
