If you’re looking to create a community tank, you have to ensure all the species living together will be happy, peaceful, and healthy. This means meeting all their requirements and mimicking their native habitats to the best of your ability. None are easier to keep together than Guppies and Neon Tetras.

How many Guppies and Neon Tetras can live together in the same tank? The answer to this isn’t so simple; it will depend on how many fish you have (or want to get) and what size tank you have. However, for an average 10-gallon tank, you can keep five individuals from each breed.

It’s important to note that this is not a hard-and-fast rule. Several variables will affect how many of both Guppies and Neon Tetras you can have in a tank. This will include things such as plants, decorations, substrate, and other tank mates.

Since Neon Tetras and Guppies share a similar temperament and preference for water conditions, they can live together quite happily. The both love a peaceful existence with the same pH balance and temperature range. But, there are a few things you have to take into consideration before you do.

You will have to pair up the specific varieties of each type of breed, so you ensure aquatic bliss while also being able to provide what they both require. This includes understanding the habits and activity of each fish, along with simulating their native environments.

What’s great is that both fish come from the Amazon River in South America. So, it will be a good idea to study that area of the world and what the general conditions are in the river and in the surrounding environment.

Water Conditions

Lighting

Both Guppies and Neon Tetras require obscured lighting conditions. They don’t need things too bright, but they do need some sort of light exposure for at least eight to 10 hours each day. The fish will also help themselves by hanging out from the middle section of the tank to the bottom.

Plants; Décor

Because the Amazon is dense with jungle vegetation and tons of aquatic plants, you want to mimic this for both Guppies and Neon Tetras.

Both of these fish like to hide and tuck themselves away among brush and foliage. Floating plants will help darken any light that’s too bright as well.

Substrate

A dark substrate is ideal for both Guppies and Neon Tetras. Not only will this help create low-lighting conditions, but it will simulate what you would find on the bottom of the Amazon River and its tributaries.

Plus, it will provide a stunning contrast between the plants, lighting, and fish.

Diet; Food

Since both Guppies and Neon Tetras are omnivores, they can each enjoy a variety of foods that include live prey and blanched veggies.

What’s fantastic about both of these fish is that they aren’t picky eaters and will consume just about anything you offer to them.

They should mainly eat things like small crustaceans, insects, worms, and fish flakes, along with frozen and freeze-dried food. But you should also give them high-protein offerings like bloodworms and brine shrimp, as well as peas, lettuce, and cucumbers.

Both fish require meals twice per day, and you should only give what they can eat in a matter of a few seconds. This will help control spikes in water parameters.

Temperaments

Both Neon Tetras and Guppies are very peaceful fish, and it’s not often they’re aggressive, especially when kept with other peaceful species. They’re active swimmers, though, and require enough space. If they feel cramped in the tank, they can be combative with other tank mates.

The only aggression you will see is when the males chase the females around during the mating time. However, if you notice either Guppies or Neon Tetras hiding far too often, it means they’re experiencing stress, or they’re sick.

Regardless, both fish breeds love to school with others of their own kind and require friends to be happy. Therefore, it’s not a good idea to have either as individuals. You want at least two of each, but more is better. In fact, six are advisable. That means you should have 12 total fish between both Guppies and Neon Tetras.

Breeding

The only problem in housing Neon Tetras with Guppies is that the Tetras will attempt to eat the fry of Guppies. The only way to control this is to have a nursery tank for the expectant Guppies. Also, both breeds can get a little cranky and aggressive when mating season comes around.

Males tend to be aggressive when chasing down females. Females will be aggressive when they’re caring for their fry. So, you will have to play referee in many instances without upsetting the fish.
