Deal breakerFish nibble at axolotl gills, and axolotls swallow small fish. Keep axolotls on their own.

What works

pH 6.5–7 suits both.
They use different parts of the tank: axolotls the bottom, silver dollars the mid.

Water side by side

The ranges do not meet, so one of them would always be too warm or too cold.

The green band is the pH both tolerate.

Size to scale

Adult length in an aquarium. A fish can swallow anything that fits in its mouth, roughly a third to half its own length for predators.
