I have a veil-tail right now! I saved the little guy from the petsmart horror cup. He’s pretty old, his color is already fading, the poor guy. Anyway, all I ever see at pesmart/petco are veil-tails! I do like the other breed’s looks slightly more but, I love the veil-tail personality. Curious and short-tempered! Lolz…my fish attacks my snail sometimes (does’nt hurt snail, because my betta lunges at the shell). My poor little veil-tail doesn’t know his efforts to hurt the snail are usless. So…I actually don’t think the veil-tail is leaving us…at least in my area. THESE GUYS ARE EVERY WHERE!
It is a sign that your Betta fish is preparing for breeding. The process follows as such:

Years ago the only betta fish available at most fish stores were male, veil-tail bettas. Around 2004 female bettas began to grow in popularity and became more prevalent in U.S. pet stores. Customers began to recognize that while they had shorter fins, their color and personality were as vibrant and varied as their male counterparts. Within a year stores began to sell a proliferation of various fin-types too. More breeders were producing double-tail and crowntail bettas and selling them at the big box pet stores like and . Today, those same stores continue to sell a variety of betta types which now include delta and halfmoon bettas in some areas. If you like the video please do subscribe, Betta fish Breeding. Bettafish

In South East Asia Betta splendens is traditionally kept as a fighting fish. The Bettas kept in Asia as fighting fishes were brown with a tinge of green and their fins were much smaller than the fins that we can see on the aquarium kept Bettas of today. If you keep a Betta fish in order to make the fight other Bettas, you will naturally have no incitements to breed fancy Betta fish with long and flowing fins that can easily be injured. Betta fighting is still popular in many parts of Asia and those Bettas can look very different from the forms that we find in aquariums. Male Betta splendens are highly territorial, and when put together in the same container they will fight until one of them dies. In the wild, a weaker male can always choose to leave the territory before he becomes deadly injured, but this is naturally impossible in a small fish bowl or aquarium. The next thing that needs addressed is keeping what ever container you use at the proper temperature. A good temperature range for spawning Bettas is 80*-84* with 82* being where most of us aim for. The most common way to keep the temp where it needs to be is with an aquarium heater. It is a good idea to set it and make sure it gets to the proper temp and keeps it there before introducing the breeding pair. It is not uncommon for a heater to malfunction and cook your fish so you want to make sure there are no problems before introducing your pair. Another way to keep the water temperature correct is with . They need a thermostat to set the temperature, but do a good job, especially if you have several spawn tanks lined up across a shelf. For that many tanks they are economical as they last longer than your typical tank heater.Bettas are pretty easy to spawn. To start I am going to give the typical US breeding set up. You will need a container, a way to keep it at the proper temperature, something for the fish to build a nest under and some place for the female to hide. The container you breed your Bettas in can be anything that holds water. The first thing to come to mind for most people is a fish tank. Some people use 10 gallons and others 5 gallons. The drawback with the larger tank is often the female can escape the male to the point he forgets about her and breeding all together. So, if you try a 10 gal and have difficulty spawning, put a divider in it to reduce the space the pair use for breeding. A 5 gallon tank makes a great spawn tank and home for the fry for the first month of their life.The male and female should both eventually get excited and flaring at each other. I like to see some aggression in the female with her flaring back and coming at the male a bit before I turn her loose. If the female is dark you will see vertical bars start to show that shows her readiness to breed. Lighter bodied girls you just have to watch their behavior. What you want to see is some female aggression, not violent but enough to hold her ground against an aggressive male, and a submissive posture. Females are submissive when they start to face the male with a nose down posture. If they come right at them head on.. they are still flirting. May females will not adopt that posture till they have been chased a bit and accept the male and his dominance. This is normal Betta courtship. It is not unusual for both fish to get nips and torn fins during the breeding process. If you see excessive aggression and one of the fish is looking stressed it is time to sleeve the one getting beat up [yes, it can be the male] or remove them entirely and try another pairing or at a later time.
