Suitable Tank Mates for Swordtails

  1. Guppies: Guppies are often considered ideal tank mates for swordtails. They are small, peaceful fish that enjoy similar water conditions and require similar diets. Guppies also come in a variety of colors, adding beauty to your aquarium. However, avoid keeping male guppies with long tail variations as the swordtails may mistake them for competitors.

  2. Platies: Platies are another excellent choice for swordtail tank mates. Similar in size and temperament, they will bring color and liveliness to your aquarium. Platies are easy to care for and can adapt well to various water conditions, making them compatible with swordtails.

  3. Corydoras Catfish: Corydoras catfish, also known as “cories,” are small, peaceful bottom-dwelling fish. They are compatible with swordtails as they inhabit different areas of the tank, reducing the chances of competition. Corydoras catfish also help keep the tank clean by scavenging for food scraps and algae.

  4. Tetras: There are several tetra species that can coexist peacefully with swordtails, such as neon tetras, cardinal tetras, and glowlight tetras. These small to medium-sized fish add a vibrant touch to your aquarium. Ensure you provide sufficient hiding places for tetras as they prefer densely planted tanks.

Fish to Avoid

While it’s important to know which fish can get along with swordtails, it’s equally crucial to be aware of fish to avoid. Some fish may exhibit aggressive behavior, be territorial, or prey on smaller fish like swordtails. Here are a few fish that may not be suitable tank mates for swordtails:

  • Bettas: While bettas are stunning fish, they are known to be aggressive, especially towards fish with long, flowing fins like swordtails. Keeping them together can result in stress, injuries, or even death.

  • Angelfish: Although angelfish are popular in many aquariums, they may see swordtails as potential prey or competition. Their territorial nature can cause harm to swordtails, especially smaller ones.

  • Large Cichlids: Cichlids, such as Oscars or Jack Dempseys, should be avoided as tank mates for swordtails. These larger, aggressive fish may view the swordtails as food or engage in aggressive behavior towards them.

  • Gouramis: While some gouramis can be peaceful, many species may exhibit territorial or aggressive behavior. It’s best to avoid pairing them with swordtails unless you have a large enough tank with ample hiding spots.

By considering the temperaments, sizes, and compatibility of different fish species, you can create a harmonious and visually appealing aquarium for your swordtails. Remember, happy and healthy fish make for an enjoyable and entertaining aquatic environment!
