what fish live with guppies

Guppies, with their vibrant colors and relatively peaceful nature, are a popular choice for beginner aquarists. However, successfully keeping guppies requires careful consideration of tank mates. Choosing compatible fish is crucial for a thriving, healthy community tank. This guide explores excellent choices and explains why certain fish should be avoided.

What Size Tank Do I Need for Guppies and Tank Mates?

Before diving into compatible species, let's address tank size. The general rule is the bigger, the better! A minimum of 10 gallons is recommended for a small group of guppies, but a larger tank (20 gallons or more) is ideal, especially if you plan on adding other fish. Overcrowding leads to stress, disease, and aggression. The more space you provide, the happier and healthier your fish will be.

What Are Some Peaceful Community Fish for Guppies?

Many peaceful community fish can coexist happily with guppies. The key is to select species with similar temperament, size, and environmental needs. Here are some excellent choices:

Small, Peaceful Tetras:

  • Neon Tetras: These tiny, brilliantly colored fish are a classic community tank addition. Their schooling behavior adds visual interest, and their peaceful nature makes them ideal companions for guppies.
  • Cardinal Tetras: Similar in size and temperament to Neon Tetras, Cardinal Tetras boast a slightly more vibrant red coloration.
  • Rummy Nose Tetras: These tetras display a distinctive red nose, and their active swimming behavior complements the lively nature of guppies.

Other Suitable Tank Mates:

  • Corydoras Catfish: These bottom-dwelling catfish are peaceful scavengers, helping to keep the tank clean. Their gentle nature and different habitat preference make them excellent companions.
  • Snails (e.g., Nerite snails): Snails help control algae growth and add a unique element to the tank. Just be sure to select a snail species that's appropriate for your tank size.
  • Shrimp (e.g., Cherry Shrimp): Peaceful and colorful, shrimp are a great addition to a community tank, providing additional visual interest and helping to control algae. However, be aware that guppies may occasionally eat baby shrimp.

What Fish Should I NOT Keep with Guppies?

While many fish are suitable, some should be avoided. Here are some species to steer clear of:

Aggressive or Predatory Fish:

  • Large Cichlids: Many cichlids are known for their aggressive behavior and territoriality, posing a significant threat to guppies.
  • Large Barbs: Some barb species can be nippy or aggressive, potentially harming guppies.
  • Betta Fish (Siamese Fighting Fish): While some Bettas are compatible with certain species, it's generally best to avoid keeping them with guppies, especially males.

How Do I Introduce New Fish to My Guppy Tank?

Introducing new fish requires a gradual process to minimize stress. Acclimate new fish to the tank's water temperature and parameters before releasing them. This usually involves floating the bag containing the fish in the tank for about 30 minutes, then gradually adding tank water to the bag over the course of an hour before finally releasing the fish.

What are Common Problems When Keeping Guppies with Other Fish?

  • Overcrowding: Too many fish in a small tank leads to stress, increased waste, and the spread of disease.
  • Aggression: Incompatible tank mates can lead to aggression, particularly towards smaller or weaker fish.
  • Disease: Introducing a sick fish can quickly infect the entire tank. Quarantine new fish before adding them to your community tank.

What Are the Best Types of Guppies to Keep Together?

There are many different types of guppies. Generally, keeping similar sized and temperaments together helps to reduce aggression and competition for resources.

By following these guidelines and carefully researching potential tank mates, you can create a thriving and harmonious community tank for your guppies. Remember that observation is key; if you notice any signs of aggression or stress, you may need to re-evaluate your tank’s inhabitants.
