Crowntail Betta - Betta splendens - Male

1 Review


There are many names for the particular betta color patterns but most are variations of blue and/or red colors. Fish pictured here are representative only. If you are looking for a specific coloration, contact a livestock department representative or simply allow us to choose one of our favorites for you!

The fins on Crowntail Bettas have a distinctive jagged, fringe-like appearance. The webbing between each fin ray is reduced so each fin ray appears elongated. On the tail, each ray can be forked with two to four "tips". This "Dragonscale" variety has individual scales that are larger than other bettas and often with dark edges to give them a scaly appearance.

Bettas are one of the most beautiful of all the anabantoids (gouramis, or "air-breathers"). Their ability to breathe air directly from the atmosphere enables them to live in the stagnant pools and puddles in which they naturally occur.

Bettas have evolved a very intense territorial aggression to the point where they are best kept by themselves. They do not tolerate other males and females are only tolerated when breeding. This natural behavior and their ability to breathe atmospheric air makes them ideal for keeping in bowls and small aquaria. As long as the water is kept relatively warm and is changed regularly, they do very well.

Bettas are carnivorous fish and must be fed meaty foods. There are many special prepared Betta diets (flake/pellet) that are excellent foods. Blood worms, brine shrimp, and plankton are also excellent as treats. Keep in mind that a betta has a stomach about the size of it's eye. It should be fed an eyeful every day to maintain it's shape and health.

It is very popular to keep bettas in a flower vase with a terrarium plant like the peace lily. This is an excellent setup for the fish but the water must be changed weekly or more and the fish fed regularly to keep it healthy. You must also keep a fair amount of space between the water level and top of the vase, because bettas need an open space to breathe atmospheric air. Also, BETTAS DO NOT EAT THE ROOTS OF THE PLANT! This is a popular misconception about this particular setup. If you happen to see your betta nibbling the roots, this is probably just out of starvation (if you aren't feeding it) or boredom.

Love this fish. Nice addition to community tank.


I've had three different male bettas in my tanks over the years since 1999 without any issues, except some larger cories eating my first one.
<br>One male is a nice addition to a community tank. Please, please don't keep them in a jar or a bowl. Minimum tank size they seem to thrive in is a 5.5gal tank. I even had one build a bubble nest repeatedly while in quarantine in my 5.5gal quarantine tank. It was awesome watching him do that. Each betta I had loved living in my 55gal tank. They would rest near the top in the floating log or to the side of the power head and swim down to the bottom. There it would rest in a cave or on the plants. Each one I had came to recognize me and would greet me from whereever they were whenever I went to the tank. Each one has a personality of its own. They didn't bother the other smaller fish in the tank at all. I have no hestitation recommending them. Just don't put them in a tank with barbs and some nippy tetras, ie. lamp (red) eyed tetras, serpae tetras, xray tetras or fish of similiar color and movements.
