Halfmoon Betta Fish

The Halfmoon Betta, in my opinion at least, is one of the most gorgeous long finned bettas you will ever get your hands on. When flared, it has a full 180 degree spread that is just amazing to see which makes this betta a favorite among a lot of betta enthusiasts.
 

Halfmoon Betta Facts

 
Here are some interesting tidbits about this fantastic creature:

  • The Halfmoon betta (often referred to as “HM” for short) is a domestic betta and does not exist in the wild. Breeding of this fine specimen began in the later part of the 1980s. (Click here if you are interested in a history lesson.)
  • If the breeding process is done correctly, their tail will take on the shape of the letter D (straight on one side and curved on the other). You will also notice that their dorsal and anal fins are larger than those on other fin types.
  • As you may have noticed in my “Plakat Betta” and “Double Tail Betta” posts, you will often see this betta mixed with the Plakat and Double Tail, resulting in these fine specimens:

  • Owning an Halfmoon betta requires a little bit more maintenance than other bettas. Mostly because they are not from a “natural” habitat and tend to pick up diseases more than other types, so it is important to keep a special eye on the water quality to avoid them getting sick.
  • Because of their large fins, they are prone to tail-biting and also tend to damage their fins more than other types, especially if the tank is too small. Give these little guys some room to move around (i.e.: don’t stick them in a 1-gallon aquarium) and they’ll be ok.
  • Let’s not forget about the “Over Halfmoon” (OHM). This is where the Halfmoon goes to the extreme and has a spread that is over 180 degrees when flared, as you can see below:

  • Some betta enthusiasts say that the Halfmoon Betta is the least aggressive betta out there. I can’t state that for a fact since I haven’t had too many bettas that have given me the “evil eye” lately, or that have been overly aggressive to my other fish, so I’ll have to take their word for it. 🙂
