Are fish filters supposed to bubble?

It is normal for aquarium filters to form some bubbles. However, if your filter is producing more bubbles than it usually does, then it is a cause for concern.

Why does my fish tank have so many bubbles?

When filling a new aquarium, a lot of agitation is created causing bubbles or a slight foam to form at the water’s surface. Cold water can hold more oxygen than warmer water, so when this cold water enters the aquarium and mixes with the warm water, oxygen is released forming those little bubbles you are seeing.

What do bubbles in a betta fish tank mean?

If you have male betta fish, otherwise known as Japanese or Siamese fighting fish, you’re probably accustomed to occasionally seeing clusters of bubbles floating at the top of the fish bowl. This means a betta is preparing to find a mate. This behavior is a strong indication of a happy, healthy betta.

Do bubbles stress fish?

If your water is not circulating or low on oxygen, then a bubbler could be just what you need! Certain fish have adapted to stagnant water, like betta, and can even draw water from the surface. In this case, the water movement caused by a bubbler can actually stress the fish.

Do bettas like bubble stones?

This allows gasses to move from the air to the water, and vice versa. An aerator or air stone works in exactly the same way. Is a common misconception that the bubbles produced by air stones oxygenate the water, but air stones are actually designed to cause surface movement — which bettas tend to dislike.

Why is my betta fish breathing air?

Most of the time, weird betta behaviors are totally normal for their species. One thing you may see your fish do is swim to the surface and stick its head out, or even try to jump above the water’s surface. It turns out that your fish is breathing when it does this. That’s right—bettas breathe air.
