|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Streamlined body; not excessively bloated; visible limb definition when swimming |
| Daily Activity | 25 minutes |
| Caloric Notes | Sinking pellets, bloodworms, earthworm pieces; feed every 2-3 days; fast 1 day/week |
| Litter Size | 500–2000 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | N/A (extensively used in research) |

|---|---|
| Growth Notes | Tadpole stage 6-8 weeks; fully aquatic throughout life; adult size in 12-18 months |
| Vaccine/Health Schedule | No vaccines; quarantine essential (chytrid carrier); maintain water quality |
| Temperature | 20-25°C (68-77°F) water temperature |
|---|---|
| Humidity | N/A - fully aquatic; water depth 15-30cm; gentle filtration |
| UVB Requirement | Not required; 12h light cycle; avoid direct sunlight on tank |
| Diet | Sinking amphibian pellets, bloodworms, earthworm pieces, occasional brine shrimp; avoid overfeeding |
| Common Issues | Red leg syndrome, bloat/dropsy, obesity, fungal infections, chytrid carrier (may not show symptoms) |
| Anxiety Proneness | Very Low |
|---|---|
| Top Triggers | Poor water quality, sudden water changes, aggressive tank mates, lack of hiding spots |
| Separation Anxiety Risk | None |
| Calming Interventions | Clean water, hiding spots (PVC pipes, plants), consistent feeding schedule, gentle filtration |
| Enrichment Needs | PVC pipe hides, live/silk plants, varied diet, appropriate tank mates of similar size |
| Cognitive Dysfunction Risk | Very Low |
| Sociability Score | 4/10 |
| Locomotion | Swimming (powerful hind legs), floating at surface, walking on bottom, lunging at food |
|---|---|
| Social | Can be kept in groups of similar size; may eat smaller tank mates; not aggressive to same-size |
| Comfort | Floating motionless at surface, gentle swimming, resting on bottom |
| Stress/Displacement | Erratic swimming, refusing food, skin discoloration, excessive surface floating |
| Breed-Specific | Fully aquatic (never leaves water); clawed hind feet for shredding food; extremely long-lived; important research animal; hardy |
| Types | Underwater clicking/trilling (males), mating calls |
|---|---|
| Frequency Range | 1,000-4,000 Hz (underwater) |
| Tendency | Low |
| Primary Modality | Lateral line system (water vibration sensing), chemical (pheromones in water), vocal (underwater clicks) |
| Tail/Body Signals | No tail; streamlined aquatic body; clawed hind feet used for food manipulation |
| Top Problems | Overeating/obesity, jumping out of uncovered tanks, eating smaller tank mates |
|---|---|
| Medical Etiology | Bloating from bacterial infection; red skin from septicemia; fungal patches |
| Fear/Anxiety Etiology | Rapid swimming away, hiding in substrate/pipes, playing dead (floating motionless) |
| Frustration Etiology | Attempting to jump out of tank; aggressive feeding behavior; glass surfing |
| Learned Behavior | Strong feeding response to vibrations; recognizes feeding time; can be target-trained |
| Cognitive Dysfunction | Minimal; extremely long-lived with consistent behavior; important model organism |
| AI-Trainable Signals | Swimming pattern (calm vs erratic), skin color/condition, feeding response, surface behavior |
|---|---|
| Context-Dependent Vocalizations | Floating at surface can be normal resting OR sign of bloat/illness - body shape differentiates |
| Interspecies Communication | Aquatic-only pet; responds to vibrations; feeding-motivated; not handleable (must stay in water); long-lived companion |
