The Crowntail Betta has become an incredibly popular pet fish, and it’s easy to see why when you start learning about it. 

When you are looking for a colorful fish that has tons of personality, you can’t do much better than this one. We will go over everything you need to know about this fish.

Crowntail Betta Appearance

This betta fish can grow up to 3.1 inches long with a maximum diameter of 8 inches. It is known for its distinct torpedo-shaped body, as well as the minimal wedding on its rays. This makes for one very unique overall appearance to say the least.

These fish are available in a wide range of colors, including dark red and blues, as well as orange. The labyrinth organ these fish have allow them to take in oxygen from the overall atmosphere, as opposed to only the water. They can therefore survive for fairly long periods when swimming around in oxygen with low oxygen levels.

Behavior

There is no question that the Crowntail Betta is quite aggressive, especially when they are kept in the same tank with other males or different fish species. While this is no surprise for experienced fish keepers, it can make caring for them difficult if you are a novice. These fish have a reputation for major behavioral problems.

The reason that this fish and so many other bettas are so aggressive is because they were bred specifically for fighting. This means that this behavior is deeply engrained in their DNA.

Natural Habitat

These fish can be naturally found in Southern Asia in slow-moving streams where the water is very clean and clear. They tend to spend most of their time in areas with dense vegetation, which serves as both food and shelter.

Crowntail Betta Care Guide

1. Tank Setup

If you want to keep a Crowntail Betta, you will need to have a minimum 10 gallon tank. You should have plenty of vegetation in the tank, as well as some caves that they can hide in.

Make sure that you keep a lid firmly secured on top of the tank, as these fish have been known to leap out. If your fish does this, there is a good chance they will die.

Due to the unique biological makeup of these fish, you won’t need to use an aeration system with your tank setup. You will, however, need to use a very good filter to keep the water clean at all times.

2. Water Conditions

It is important that you keep the water in this betta’s tank within a temperature range of 76 to 80 degrees Fahrenheit. Make sure that the pH level of the water is somewhere from 6.4 to 7.0, and a water hardness rating of 2 to 5 Dkh. These are the most ideal water conditions to keep your betta healthy on a daily basis.

Remember to change out the water in the tank every two to three days. You’ll want to be careful not to get rid of the helpful bacteria, as it is good for your fish’s health.

3. Crowntail Betta Food

You will need to make a point of giving these fish high protein foods on a daily basis. Some of these foods include blood worms, black worms, brine shrimp, and black mosquito larvae. You can also give them fish flakes or pellets. The best live foods for these bettas include white worms, wingless fruit flies, and others.

If you choose to give your fish pellets, you’ll want to limit them to two or three pellets per meal. Keep in mind that the diet you have your fish on will determine just how bright and beautiful its colors are.

Common Health Problems

These bettas are prone to certain diseases, some of which can be life threatening if gone untreated. This includes Swim Bladder Disorder, which usually results from overfeeding or a bacterial infection. You will notice your fish floating on its side and having a hard time swimming.

Some of these fish also develop tumors, which can be incredibly dangerous as well. You might notice a bump or lump somewhere on your fish’s body. These lumps can appear anywhere on a fish, and they have a variety of causes.

There is another disease called “velvet” that causes a yellowish rust coloration to form on the fish’s scales. This is often a result of stress and/or poor water quality. While it is not immediately dangerous, it can cause certain health complications over time.

Crowntail Betta Breeding

Male crowntail bettas make a bubble nest around the floating plants in the tank, which they will eventually fertilize. If you notice groups of bubbles forming on the top of your tank, it probably means that your fish are ready to begin mating.
