Is it true that my Betta fish is a low-maintenance kind of fish?

No, Betta Fish needs high maintenance and a specific type of care. They need clean water, ample space, and the right temperature requirements to stay healthy.

Here are the basic requirements and equipment in Betta Fishkeeping:

  • Nets

To safely and gently catch your Betta, use an extra-soft nylon cushion that doesn’t pull at fish scales.

  • Gravel Vacuum

Gravel Vacuum makes water changes easier with this double-duty cleaner, which siphons as it removes waste buildup from your gravel bed. This is very helpful for your Bettas.

  • Scraper

This equipment controls the growth of algae. It reaches areas that are harder to clean. Scraper makes regular aquarium maintenance easier.

  • Filtration

In a larger aquarium with filtration, be sure the intake and water outflow are gentle. If a single Betta is kept in a bowl environment, filtration may not be practical, so complete water changes should be performed weekly.

  • Heater& Thermometer

Heaters and thermometers ensure that the Bettas can have the ideal temperature for their environment. Temperature range between 73°F and 81°F (23°C – 27°C ).

Are Betta fishes carnivores?

It is recommended to feed your betta fish two to four pellets, once or twice per day. Pellets expand when placed in water and are very filling for your betta fish.

Can my Betta fish get along with other fishes?

Yes, if your tank can accommodate the needs of the fish inside it. Note that, Betta fish need the right mix of non-aggressive fish to share their aquarium. Bettas usually attack scales, gills, and tails and will respond if bitten.

Avoid combining Bettas with……

  • Angel Fish
    • Red Tail Sharks
    • Gold Fish

  • Cory catfish
  • Neon and ember tetras
  • Ghost shrimp
  • African dwarf frogs
  • Guppies
  • Kuhli loaches

In addition, a 10-gallon tank can comfortably house your Betta as well as 3-4 other fish. Bettas will not be happy in tanks that have a lot of ‘busy’ fish that are hyperactive and are always darting around. Instead, they prefer fish that are calmer and not too colorful.

I have two male Bettas. Is it a good idea to combine them in one tank?

No, it is not a good idea. Male Bettas are very aggressive. They are bred to fight with each other. Male Bettas are naturally territorial and will almost always show aggression when they encounter other males in the wild. Two male Bettas in the same tank will fight each other. Note that, Betta attacks can cause severe injury, infection, and even death, so keeping males separate is crucial to their well-being.
