Watch outOscars grow to 12 inches and need 75 gallons, far more than a tank set up for white cloud minnows.

What works

pH 6–8 suits both.

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.
