* Lack of Filtration: Fishbowls have no filtration system, leading to ammonia and nitrite buildup in the water. This is toxic to Bettas and can cause serious health problems.
* Limited Water Volume: Fishbowls are typically very small, which means the water quality deteriorates quickly and the Betta doesn't have enough space to swim.
* Temperature Fluctuations: Fishbowls are prone to temperature fluctuations, which can stress Bettas.
* No Oxygenation: Fishbowls lack adequate surface area for oxygen to dissolve into the water, making it difficult for the Betta to breathe.
A filter and air pump are essential for a healthy Betta tank.
* Filtration: A filter removes waste products, ammonia, and other harmful substances from the water, keeping it clean and safe for your Betta.
* Oxygenation: An air pump provides a constant supply of oxygen to the water, making it easier for your Betta to breathe.
* Temperature Control: A heater can be used to maintain a stable temperature, ensuring the Betta's comfort.
Here's a good setup for a Betta:
* Tank Size: At least 5 gallons (ideally 10 gallons or more)
* Filter: A small filter specifically designed for Betta tanks is ideal.
* Air Pump: A small air pump with an airstone is recommended for extra oxygenation.
* Heater: A heater to maintain a temperature of 78-82°F (25-28°C).
* Substrate: A gravel or sand substrate that is safe for Bettas.
* Plants: Live or artificial plants provide hiding places and enrich the environment.
* Water Changes: Regular water changes (25% every week) are crucial to maintain good water quality.
Remember, a well-maintained tank with a filter and air pump provides a much healthier and happier environment for your Betta than a fishbowl ever could.
