QUESTION: What size tank is ideal for fish?

ANSWER: A 20-gallon-aquarium is ideal because it is easier to maintain healthy water conditions—and your fish will appreciate it, too. The general rule is 1 gallon per inch of fish. The experts at the aquarium store can help you select fish that will thrive together.
