Betta fish tank mates

There are several things to keep in mind before choosing betta fish tank mates.

Betta, also known as Betta splendens, is quite famous for its territorial and aggressive act. Small tanks and slow-moving fishes can trigger these behaviors. This behavior can be reduced if kept with other compatible fishes in a large tank.

There are a few things that you should keep in mind before selecting any partner for them. These will help reduce aggression and avoid getting harmed or harm other fishes.

  • Large fin/tail fishes – Other fishes can be mistaken as Betta from their large fins and tails. Bettas will nip on their fin/tail if kept together. So, avoid keeping these fishes with Bettas.
  • Single fish – Never keep any single fish from other species with Betta. Otherwise, they will keep harassing them, which can stress the other one. Keep other species in a group of 4-5 fishes who move in a shoal. It will move Betta’s focus from any individual fish.
  • Predatory fishes – You should avoid large and predatory fishes as these can harm your Bettas by continuously nipping and biting their majestic tails or fins.
  • Same temperament fishes – You should avoid keeping the fishes who share the same temperament or are territorial. These fishes can get in a fight with your Bettas over territory and result in hurting both of them.
  • Set up a second aquarium – To set up a tank for Betta and other fish species, make sure to add the other species before Betta.

It will help them set their territories and become comfortable in the new environment. Prepare the second aquarium with the right conditions to keep Bettas separate.

Betta fish lifespan will also increase if you keep them in the right community tank.

It will also help if anything goes wrong with the already set up tank.

Considering Tank Sizes

Betta Tank Mates 5 Gallon Aquarium

A 5-gallon aquarium tank is very small for keeping a betta and other fish. It won’t provide Betta enough space to swim with other fish around. They will easily get aggressive, which can result in a fight even with a compatible mate.

So, we won’t recommend you to have a 5-gallon tank for this purpose. This small aquarium is suitable only if you are planning to keep a single Betta in it. They are anti-social creatures, so that they will live happily in a small aquarium all alone.

Instead of fishes, you can stock the tank with various plants, such as Amazonian Sword Plants or some Java Ferns. You can also add other decorative ornament or artificial plants to the tank.

Just make sure it is not made up of hard plastic but other soft materials. The Betta can get hurt or get scratched from it. Also, make sure everything is fixed firmly. The Bettas are known to dig and uproot plants and other ornaments.

If you still want to add some live creature to the tank, you can add snails or shrimps. They will keep the tank clean and live peacefully with your Betta.

Betta Tank Mates 10 Gallon Aquarium

A 10-gallon aquarium is large enough for keeping other species of fish with your Betta. But the tank should be set up right so that everyone gets ample space. You can add more plants and bogwood logs to create hiding space for other fishes and block Betta’s view.

As we discussed earlier, you can add artificial plants as well, but they should not be made from hard plastic or damage your Betta’s fins. Also, the fish species that we discussed above will be perfect for keeping in a 10-gallon tank.

The bottom-dwellers like Loaches and Catfishes will be perfect for a tank of this size. You can also add snails, shrimps, or frogs to add variety to your small capacity tank.

Non-fish Creatures for Bettas

You can add non-fish species to your Betta tank as well. The main benefit of keeping these creatures is that they will add variety to your aquarium. These creatures can become good betta fish companions for both males and females.

These creatures should not be too small; otherwise, they will become dinner for the fish but small enough not to harm or disturb other fishes. The non-fish species that will be suitable for your Betta tank are –

  • Mystery snails These snails are colorful and are famous for their ability to keep the tank shining. They won’t get big enough to disturb your Betta and quietly eat any leftover food and algae from the tank.
  • Malaysian Trumpet snails – These species of snails are nocturnal. They are algae eaters. So, they will wander the tank at night and do all the cleaning while your Betta sleeps. During the day, they will burrow under sediment.
