However, the most common combinations are either a merle or marble coat pattern, a calico coat pattern, or a rainbow coat pattern.

Discontinuous genetics are what cause multicolored female bettas. When two multicolored parents breed together, the offspring will always be multicolored no matter what.


How to Care for a Multi-Colored Female Betta?

When it comes to betta fish care, the most important thing is to provide excellent water conditions. While many people think that bettas are okay with dirty water, this is far from the truth. Bettas are pretty sensitive fish and can be affected by small changes in the water quality. For example, dirty water can cause a bacterial infection which can be fatal if it’s not diagnosed and treated immediately. 

As far as water temperature goes, bettas prefer a temperature in the range of 21 to 25 degrees Celsius. While it’s possible to keep a healthy betta in cooler water, they tend to be happier in warmer water. That being said, changing the water temperature too often can stress the fish out and make them more susceptible to disease. For this reason, it’s recommended to keep the water temperature consistent.

It’s recommended to keep them in a 5-gallon tank with a heater and filter. As far as the water is concerned, it should be kept in the range of 21-25 degrees Celsius. Bettas are herbivorous fish and therefore, they prefer a diet rich in plant matter. You can provide your rainbow merle betta with either pellets or flake food. However, it’s important to provide them with access to live plants as well.

A marble betta fish is bred by cross-breeding two bettas that already have the marble coloring pattern.
