In short: Germany's 1997 expert report on minimum requirements for keeping reptiles is being revised and will also cover amphibians. As of October 2026, there is only a draft from the federal agriculture ministry (BMLEH) and comments from bodies such as the German Federal Veterinary Association; no final version has been published and no new minimum sizes apply. The direction is clear, though: more focus on hygiene, measuring equipment, quarantine and welfare-problem morphs.
What is Germany's 1997 reptile report?
The report on minimum requirements for keeping reptiles (Gutachten über Mindestanforderungen an die Haltung von Reptilien) is dated 10 January 1997. It was written by an expert group on the welfare-friendly keeping of terrarium animals on behalf of the federal agriculture ministry of the time.
It is not a law. Veterinary authorities and courts use it to interpret the general duties of the German Animal Welfare Act (§ 2 TierSchG), meaning what counts as suitable housing. The report itself calls its dimensions guide values.
How does the old report calculate enclosure size?
Sizes are given as multiples of the animal's length: head-body length for lizards, total length for snakes. For a bearded dragon, that is 5 × 4 × 3 head-body lengths; for pythons up to 2.5 m it is 1.0 × 0.5 × 0.75 total lengths. The widely used version has tables for chameleons, lizards, crocodilians and snakes, and none for amphibians.
Many of these values are now considered tight. Our terrarium size and climate chart compares them with current recommendations.
Where does the revision stand?
The Federal Ministry of Agriculture, Food and Regional Identity (BMLEH) has prepared a draft of a new report on minimum requirements for keeping reptiles and amphibians and asked professional bodies for comments. Based on our research, the draft text itself is not public; its content can only be inferred from the published statements.
| Date | What happened | Binding? |
|---|---|---|
| 10 Jan 1997 | Reptile minimum-requirements report published | Guide values used by authorities |
| 2025 | BMLEH drafts a revised report for reptiles and amphibians and opens a consultation | No, draft |
| 5 Dec 2025 | Federal Veterinary Association (BTK) and the veterinary animal welfare association TVT submit comments | No, recommendations |
| 16 Dec 2025 | BTK statement published in the German parliament's lobby register | No |
| As of October 2026 | No published final version known to us | The 1997 report remains the reference |
When the new version will appear, and with which numbers, is open. We deliberately do not quote any new minimum sizes, because none have been published.
What do Germany's vets ask for?
The BTK statement of 5 December 2025 welcomes the revision and especially the inclusion of amphibians. Its main requests:
- Group housing: limits for territorial species should refer to adult animals, since territorial fights mostly start at maturity.
- Egg-laying sites: required only where relevant, for sexually mature females.
- Measuring: thermometers and hygrometers should show or store minimum and maximum values.
- Quarantine: clearer wording, no mixing of holiday-boarded animals into a collection, and a pointer to further hygiene measures.
- Salmonella: extra information on infection risk is welcomed.
- Breeding: a note on the permit required for commercial breeding under § 11 TierSchG.
Welfare-problem morphs
The BTK suggests a separate section on breeding forms with welfare problems (Qualzucht) and names two examples.
| Morph | Species | Problem according to the BTK |
|---|---|---|
| Spider and related morphs | Ball python | Inner-ear malformation; signs from head tilting to disorientation |
| Lemon Frost | Leopard gecko | Strongly increased tendency to develop tumours (iridophoromas) |
| Other notable forms | Various | Scaleless animals, albinos of day-active species, colour changes that disrupt communication |
The list is explicitly not complete. The BTK recommends a reference to the existing breeding ban for such animals under § 11b TierSchG.
What does the TVT add?
The TVT statement, also dated 5 December 2025, calls the draft detailed and a good basis and welcomes plans to update it regularly. Points relevant to keepers include:
- Enclosure size must allow temperature and humidity gradients and a safe distance from lamps; the TVT gives no figures.
- Single housing is appropriate for most species; in groups every animal needs access to food, water and basking spots.
- Glass blocks UVB completely, fine mesh reduces it a lot, and UV lamps must be checked or replaced regularly.
- Digital thermo-hygrometers with min/max memory are preferred, and husbandry data should be recorded.
- Peat substrate is rejected for climate reasons, and Lemon Frost should be named clearly as a welfare-problem morph.
- The statement indicates that the draft rejects letting reptiles roam free in the home and includes a form of protection for existing setups; the TVT wants that protection excluded where housing is likely to cause suffering.
What changes for keepers right now?
Legally, nothing yet. Until a new version is published, the 1997 report stays the reference for authorities. Sections 11 and 11b of the Animal Welfare Act already apply today.
Practically, the draft shows the direction: measure more precisely, keep records, take quarantine seriously and do not breed animals with known welfare-problem traits.
What can you do already?
| Step | Why | Typical price in 2026 (approx.) |
|---|---|---|
| Digital thermo-hygrometer with min/max | Catches night-time or heat spikes you would miss | 10–25 € each |
| Infrared thermometer | Checks surface temperature at the basking spot | 15–40 € |
| Husbandry log | Records feeding, sheds, weight, vet visits and equipment | 0–10 € |
| Quarantine tank for new animals | Keeps disease out of your collection | 30–80 € |
| Enclosure larger than the 1997 minimum | Real gradient and more movement | 200–800 € depending on size |
| Structured 3D background | Turns the back glass into climbing and resting space | Depends on size and design |
Minimum sizes describe length, depth and height, but the animal cares about usable surface. A rock background with ledges and caves, side roots and several hides and caves add levels without a bigger tank. The size guide shows which background fits your enclosure.
Ask questions before you buy an animal
Ask the breeder about the morph and its background. Animals carrying the Spider gene or Lemon Frost should not be used for breeding, and beginners do best with wild-type colours or well-studied colour forms.
Common misunderstandings
- "The new report already applies." No, it is a draft.
- "The report is a law." No, it gives guide values that authorities use for interpretation.
- "Spider ball pythons are now banned." § 11b concerns breeding, not keeping existing animals.
- "There are new minimum sizes." None have been published.
FAQ
Do I have to rebuild my terrarium now?
Not because of the draft. If your enclosure only just meets the 1997 minimum, though, a bigger one is worth it for the animal anyway.
When will the new report take effect?
To our knowledge, the ministry has not named a date. A report is published and then used by authorities, rather than coming into force like a law.
Will frogs be covered?
That is the plan: the draft covers reptiles and amphibians. Its values are not public yet.
Is this legal advice?
No. It summarises public statements. For specific questions, contact your local veterinary office or a reptile vet.
