Betta Fish FAQ: Your Common Questions Answered
With short questions, quick answers, and links to more detailed articles should you want them, this is a must-read for all betta keepers, to get a good background and general understanding of the breed.
Betta Fish Tank Size: What Size Tank Do Betta Fish Need?
Yes, betta bowls and vases are common. Yes, they are cheap. Yes they’re seen everywhere and sometimes they do look nice. But they are still very wrong.
Like all fish, betta thrive when given room to live and exercise, room to perform natural behaviors and a high water quality that’s simply un-achievable in a tiny, tiny bowl.
Providing a large enough tank for your betta is the very first and most important step toward caring for them properly.
But what size tank is best for a betta? Find out by clicking the following link:
Heating: Do Betta Tanks Need a Heater?
This is usually a very bad thing!
Betta are tropical fish, they naturally live in warm water and indeed they need this to survive. Optimum temperature for a betta tank is 78 to 80 degrees Fahrenheit.
It’s safe to say that the vast majority of places in the world will have room temperatures that fall way below this, particularly at night, so every betta tank really should be fitted with a heater.
In this article we discuss betta tank heating requirements, how to choose the best heater for your tank, and even what you can do in the emergency case of your heater failing, to keep your fish alive.
Filtration: Should a Betta Tank Have a Filter? Of Course!
It doesn’t take long for this waste to build to harmful levels. In fact, with ammonia and nitrites, the chemicals released from decomposing fish waste, even the tiniest trace present is extremely dangerous for your fish.
This is why filtration is needed, to biologically clean the water of these dangerous chemicals and keep the water in the tank at a high quality for your betta to breathe and live in.
But that’s not all, filters also catch and remove a lot of the physical dirt and detritus that would otherwise float around in the water, making it look unsightly and unclean. I don’t know about you, but this isn’t how I want my aquariums to look.
So a good filter is needed both for fish health and aesthetics and there are a wide variety of filters of available, most of which do at least an acceptable job of keeping the water of a tank clean.
But bettas do have special requirements so you can’t just rush out and buy any old filter. You need to make an informed decision. Learn what you need to know by clicking here:
Aquarium Filters 101: Filter Media, Maintenance and More
But there’s more yet to consider!
Filters have removable media that perform different jobs and clean the water in different ways. It’s important to understand these differences, and what options for filter media are available to you so you can make the right decisions.
In this article we discuss: Sponges, pads and floss, ceramic tubes, activated carbon, what each of these does in a filter and whether you need them or not. We also touch upon filter maintenance and keeping things running optimally.
Bubbles: Do Betta Tanks Need Aeration?
Aeration in a betta tank isn’t essential and in fact is usually quite strongly discouraged. It’s not that you must never have it, you can in the right set-up when taking into account the right considerations. However, usually it’s a big ‘no-no’.
But then, some of the filters most highly recommended for betta tanks actually work on an air pump and rising bubbles system. So which is it?
Learn about the ins-and outs of aeration, air pumps and what you need to consider for betta tanks here:
Lights: Do Betta Fish Need Light? If So, How Much and What Type?
Betta fish need a daily cycle of light and dark to mimic night and day in nature, a cycle that sets their body clock and regulates their sleep, waking and feeding times. Without such a lighting cycle, the health of your betta fish will rapidly deteriorate.
But with so many different fittings, bulbs, spectrum’s and strengths of aquarium lighting available, knowing what’s suitable for a particular tank isn’t immediately obvious.
Discover in this article all the ins and outs of lighting for your betta aquarium. The lights you should choose, the ones to avoid, how strong a light for how many hours per day…and much more besides!
Substrate: Gravel? Sand? Marbles? Which Is The Best to Use?
Substrate isn’t used just to make an aquarium more attractive, it plays a few very important roles in the health of your aquarium.
Substrate provides a home to highly beneficial bacteria, creates a more natural looking and suitable environment for your fish and in doing so decreases stress, while also providing root anchorage and a home for any living plants.
Therefore, the particular substrate you choose can have a dramatic affect on the inhabitants in your aquarium.
So which should you choose? Gravel? Sand? Marbles? Something else maybe?
In this article we discuss the ins and outs of using substrate, the pros and cons of the most popular types available and help you to make the right decision.
Cycling: What Is ‘Cycling A Tank’? Why Must You Do It BEFORE adding fish?
Fish waste very quickly turns to ammonia and the presence of ammonia, in even the tiniest of amounts, is highly toxic to fish. Furthermore, ammonia gets turned into nitrites – another extremely toxic chemical to fish.
In mature and established tanks, there are colonies of friendly bacteria that convert ammonia into nitrites, and this in turn into nitrates. This is known as the ‘nitrogen cycle’ (as well as by many other names.)
Luckily, nitrates in low concentrations are harmless to fish and you remove these from the tank by way of frequent water changes, before they ever reach harmful levels.
However, in a new fish tank the necessary bacteria do not yet exist. They take many weeks to develop. And putting your betta fish into the tank BEFORE bacterial colonies have a chance to establish means your fish has to live and swim in an incredibly harmful ammonia and nitrite soup.
To prevent this from happening, you have to ‘cycle’ your tank before you ever introduce your fish.
In this article, we detail the process of nitrification, why you simply must understand the nitrogen cycle, why and how to test your water quality, and how to ‘cycle’ your tank to grow beneficial bacteria before you even introduce your fish.
Food: How to Feed Your Betta Fish? What Do They Eat?
Betta fish are carnivores and need a diet very high in protein, which means shrimp, worms and larvae are best. Like all animals, they also do best when fed a variety of foods to provide a balanced diet containing the wide array of nutrients they need to truly thrive.
The ‘betta-in-a-bowl’ where the fish lives off a plant? It’s just totally wrong. And so are many ‘generic’ fish flakes or pellets.
Just important as what you feed your betta, is how much and how often. Obviously you don’t want your fish to starve, but over-feeding is a very serious and common problem too.
In this article we discuss the betta diet, what they would eat in the wild, what you should feed them in your aquarium, how much to fed them and how often. You’ll soon be feeding your betta exactly in the way they need!
Betta Fish Diseases, Symptoms and Treatment Guide
In this guide, we cover preventative measures you should employ to help keep away any disease. We cover the most common illnesses and diseases that affect betta fish, and we offer advice on treatment and how to recover when the unfortunate does happen.
Water Changes: A Step-by-Step Guide to Partial Water Changes
Because a fish tank is a closed environment, anything that goes into it remains. This means all the food you put into the tank either gets converted to waste by your fish, or is uneaten and left to rot. This results in a build up of harmful chemicals in your aquariums water.
Yes, a filter is an indispensable tool for converting highly toxic substances into less harmful ones, but those less harmful ones are still a danger if left to build into high enough concentrations.
Water changes are the essential way for you to ultimately remove these accumulated harmful chemicals, something you simply MUST do on a regular basis.
In this article we discuss in depth why water changes are so important, why you should only perform partial changes, how much you should change, how often – and more besides – so that your fish has quality water to live in.
