Types of Rainbow Betta Fish

There are three main types of rainbow Betta fish, namely:

– The standard rainbow Betta: This is the most common variety of rainbow Betta kept as a pet. It has a light-coloured body marked with dark vertical bars and a bright red stripe that runs from the head along the spine to the tail. The standard rainbow Betta is a peaceful, easy-to-maintain fish that is suitable for both beginner and experienced aquarists.

– The leucistic rainbow Betta: This is a rare version of the standard rainbow Betta that is less common to see. It has a pale or white body with dark-coloured fins. White bodies and fins are not an indicator of poor health; it’s just a genetic trait that is passed down from the parents.

– The albino rainbow Betta: This is a rare variety of rainbow Betta that is even rarer to see. It has a pale body with dark purple or black dorsal, anal, and caudal fins with or without red bars. Purple Betta is a bit less common than red, while albino varieties are even rarer to see.

Rainbow Betta Fish Diet and Feeding Habits

Rainbow Betta fish can live in environments of almost any pH level, ranging from 3 to 9 (with an ideal pH level of 8.0 being best for these fish). If you feel you can safely keep a rainbow Betta in your home without the risk of it escaping, you can feed your new companion any type of tropical aquarium diet. There are, however, a few things to keep in mind before feeding a rainbow Betta fish.

First, these are small fish, so you need to ensure that the aquarium tank you’re using has adequate space for them to move around freely. If your tank is too small, your rainbow Betta may feel crowded and begin to swim around nervously. This behavior results in poor water quality and increased stress on the fish. Rainbow Betta fish are omnivorous and can be fed a diet that includes both meaty foods such as bloodworms and brine shrimp, as well as plant matter such as sinking veggie pellets, flake food, and fresh fruits and vegetables.

Differences Between Male and Female Rainbow Betta

In addition to the three main types of rainbow Betta fish, there are other important differences between male and female rainbow Betta fish. Male rainbow Betta fish sport a bright red color on their dorsal and anal fins, while female rainbow Betta fish has a pale body with dark fins. You can distinguish male and female rainbow Betta fish by keeping an eye out for the presence of eggs in the female’s ovipositor; she will likely be keeping her tail curled close to her body. Unlike male rainbow Betta fish, which are straightforward in their reproduction habits and spawn only once per year, female rainbow Betta fish spawn many times over a year, resulting in a much higher likelihood of producing offspring.
