The Answer Key
- 1: B (16-18°C is the sweet spot; higher temps cause heat stress).
- 2: B (Gravel is the #1 cause of impaction/choking).
- 3: C (Cycle first! Ammonia and Nitrite must be 0 for safety).
- 4: C (Earthworms provide the most complete nutrition).
- 5: B (Tubbing saves lives during emergencies or cycle failures).
- 6: C (Aloe vera is a major gill irritant—always read labels).
- 7: C (20 Gallons Long provides the surface area they need to roam).
- 8: B (Weekly checks catch dangerous spikes before they cause harm).
- 9: C (Sponge filters are gentle and perfect for low-current lovers).
- 10: B (Forward curled gills are a classic sign of aquatic stress).
- 11: B (Soft and smooth is the rule for their delicate skin).
- 12: B (Partial weekly changes keep nitrate levels under control).
- 13: B (If params are toxic, get them into fresh water immediately).
- 14: B (A curled tail tip is a 'red flag' stress indicator).
- 15: C (They have no eyelids! Dark hides are essential).
Answer Key & Explanations
1. B
20 gallons long is the minimum for one adult to provide proper floor space.
2. A
16-18°C is the ideal range; anything above 22°C causes severe heat stress.
3. D
Fine sand is safe; gravel and pebbles are fatal impaction hazards for axolotls.
4. C
The nitrogen cycle turns ammonia into less harmful nitrates over several weeks.
5. B
Healthy adults usually eat every 2-3 days, while juveniles require daily feedings.
6. C
Aloe vera can coat and irritate an axolotl's sensitive gills, causing breathing issues.
7. A
The feathery stalks are external gills that absorb oxygen directly from the water.
8. B
Tubs lack filtration, so 100% daily water changes are vital to prevent ammonia burn.
9. D
White fuzz on gills is usually fungus, often caused by stress or poor water quality.
10. A
Floating is generally caused by air trapped in the gut or impaction from gravel.
11. C
Axolotls should be kept in species-only tanks to avoid injury from fish nipping.
12. B
Axolotls lack eyelids and are sensitive to light; they prefer dim or shaded setups.
13. D
Sponge filters are perfect as they provide aeration with very gentle water movement.
14. A
Tap water contains toxic substances like chlorine that must be neutralized before use.
15. C
Axolotls are native to the Lake Xochimilco canal system in Mexico City.
