The Short Answer
Guppies need 74-82F water. Axolotls eat any fish small enough to swallow. Both problems happen at once.
Why This Works Badly
Guppies are tropical fish that don't tolerate cold water. Axolotls eat them as live food. The combination guarantees rapid death for at least one species.
Temperature Compatibility
Guppies need 74-82F. Axolotls need 60-68F. No working overlap.
Even at the overlap edge (around 72F), guppies have weakened immunity and axolotls are stressed. Both species die from related but different causes.
How Axolotls Injure Guppies
Adult axolotls eat guppies whole. Multiple guppies in a tank typically disappear within 1-3 days.
Symptoms to Watch For
- Guppies disappearing
- Axolotl regurgitating fish parts
- Both species lethargic
- High waste from temporary mixed bioload
What to Do Instead
If you want guppies, get a heated 10-gallon tank for them separately.
