The Rubra betta is a striking fish with vibrant red and gold colors. I kept it in a 20-gallon tank with live plants and it’s very active. The water conditions were easy to maintain with a gentle filter and regular water changes. It’s a great addition to a community tank.

I noticed the male had a strong red operculum, which is very distinct. The fish is peaceful when given space and cover. I removed a brooding male after a few weeks to prevent fry from appearing. Water pH stayed stable at around 6.2.
