Guppy Fish and Tetras – Are They Good Tank Mates?

Guppy fish and Tetras make good tank mates. Both species of fish can be kept in the same tank. Guppies and Tetras are both peaceful, eat the same food, and tolerate the same tank conditions.

Tank Size

When keeping both guppies and tetras, aim for a 20-gallon fish tank. The more space the better. And, the more fish you have, the larger the aquarium ought to be.

Both guppy fish and tetras like to live in schools which means that they swim around together. A 20-gallon aquarium is ideal for 10-15 fish.

Tank Maintenance

Filtration is important when keeping fish in tanks. A filter such as the Aqua Clear – Fish Tank Filter is a good choice for tetras and guppies. It’s an HOB filter that uses a 3-stage filtration mechanism: mechanical, chemical and biological.

Water Conditions

Both guppies and tetras can thrive in the same water conditions. A good heater for your tank like the Eheim Jager Aquarium Thermostat Heater is a great investment to maintain stable water temperatures. A temperature around 72-74 °F (22-24 °C) is perfect for both guppy and tetras.
