Can Axolotl Live With Betta Fish?
No, axolotls need 60-68F water while bettas need 76-82F, and axolotls may bite a betta during feeding.
Why
- Axolotls require 60-68F. Bettas need 76-82F. There is no temperature range where both species thrive.
- Axolotls are coldwater amphibians. Above 74F they experience stress and become susceptible to fungal infections.
- Bettas are tropical and slow down significantly below 76F. Below their ideal range they are lethargic, stop eating, and get sick.
- Axolotls may bite at a betta during feeding, and a betta's flowing fins look like prey to an axolotl's hunting behavior.
What could go wrong
You must choose between overheating the axolotl or chilling the betta. Either way one species suffers and eventually dies.

AquaClear 30 Power Filter
Oversized filtration is what lets you stock two species together without water quality crashing. Rated for a tank slightly larger than the 20 gallon minimum.

Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Axolotls do well with white cloud minnows or mystery snails in a coldwater setup. Bettas do well with corydoras or nerite snails in a tropical tank.
