What Do You Need For A Fish Bowl?

Beneficial Bacteria

When you hear bacteria its normal to think of the bad kind of bacteria but all bacteria are not bad. Without good bacteria, we wouldn’t have a life here on earth. It’s essential to have good bacteria in order to help keep your fish and its ecosystem alive.

Here is what beneficial bacteria looks like under a microscope.

As your fish eats its meals and then excretes, the debris will settle at the bottom of the tank. Over time this can be very harmful to your fish. Having good plants can break this excrement up then release oxygen back with the particles. As this happens you have excess chemicals these can be brought down more with good bacteria and water changes.

Using both effective water changes and good bacteria can eliminate these harmful chemicals making your fish happy and healthy.

Good Aeration

Aeration is the process of allowing particles, water, and nutrients to move freely with roots to strengthen plants. With good aeration, the soil will not be too compact to not allow proper airflow. This can lead to plants not providing sufficient living conditions.

Good aeration is essential to allow fish to beath in good, clean, quality oxygen. Yes, fish breathe in oxygen just like you and me. knowing that means that it’s essential for them to have good aeration.

With a round bowl it’s a good idea to have plants for aeration but also would be nice to have a waterfall filter or spray bar. Space is essential so having too many means wouldn’t do any good for the fish.

Room Temperature Water

Heaters are essential to maintaining water temperature so having a good reliable on really can help extend the lively hood of your fish. Knowing this it's a good idea to have a thermometer present to ensure that the water doesn't go too high.

When you are adding water to your fishbowl it’s important to note that the source will determine the overall outcome. Tap water or spring water is good to add to your fishbowl. However, making sure to add a conditioner to the water will help with chemicals.

What Makes A Fish Bowl Bad?

What makes a fishbowl bad is precisely the opposite of what makes them good. Without proper aeration, your fish will suffer as well as beneficial bacteria. Without proper water parameters in place, the fish will become stressed.

This is a bad example of having a round fishbowl. Unfortunately betta fish are not good for keeping in fishbowls because they should have at least 5 gallons per betta fish to move around, interact, and for excretions. Betta fish will also fight in close courters so it’s best to give them enough space to roam.
