Origin and descriptions
Originating from Thailand, the delta tail betta fish have become extremely popular pets and first-time aquarium owners are often unaware of what type of care they require. The fish is a common species that is relatively inexpensive, easy to care for, and comes in a variety of beautiful colors.
Once you’ve bought your new pet, there are several things you can do to keep it healthy and happy. In order to prevent illness and disease, following a proper diet is essential.
Species profile
The delta tail betta fish belong to the family of fishes called Osphronemidae. They are native to Thailand, Malaysia, Indonesia, and Cambodia.
They have a very distinctive look. Instead of having a regular, diamond-shaped tail fin like most other betta fish, they have tails that are different in shape. Because of their unique appearance, they’re often referred to as delta-tailed or triangle-tailed bettas. Although not technically a type of Siamese fighting fish, they were bred from them and share many similar characteristics with them.
Habitat
In their natural habitat, delta tail betta fish live in brackish water and small ponds. The best way to replicate these conditions in a home aquarium is to keep your tank at around one-third full; that gives your fish plenty of room to swim but not so much water that it will grow stagnant. (If you choose a smaller container, you’ll also need to change it more frequently.)
These fish thrive between 68 and 84 degrees Fahrenheit, so make sure your temperature stays within that range. If you don’t have a thermometer, stick your hand in: If it feels warm enough for you to leave it there comfortably for 30 seconds or so, then your water should be fine.
Finally, as with all freshwater fish, your delta tail betta fish needs an air pump and an air stone—but only if he doesn’t come equipped with his own built-in bubble maker!
Delta tail betta fish size
Their sizes range from 2-3 inches (5-8 cm) in total length.
Tank size
Due to their small size, the minimum recommended tank size is 10 gallons (38 gallons)
Tank requirements
The first thing you need to know about setting up a tank for your betta fish is that they are quite particular. If your tank doesn’t meet their needs, they may not survive. A healthy betta should be swimming in a large but well-filtered tank of at least 10 gallons, with plenty of plants and hiding places.
For example, a 20-gallon aquarium would work best for one or two bettas. Bettas like hard water (with a pH between 7.0 and 8.5) so make sure to test it before buying your fish. Bettas also prefer cooler temperatures, so keep their tank away from direct sunlight or heat sources like space heaters.
As long as you provide them with these basic requirements, there are many other things you can do to make your betta feel even more at home, add some color!
Bettas love bright colors, so decorate their tank with ornaments and plants in shades of blue and purple. You can also buy a special betta-friendly plant like anubias or java fern. Another way to give your fish a fun place to explore is by adding a bridge or cave for them to swim through.
Delta tail betta fish tank mates
It is generally not a good idea to house multiple betta fish in a single tank. They are territorial and can become aggressive with each other, causing harm and even death. If you want to keep multiple bettas, create individual homes for them. Also, note that some fish do not mix well with or cannot live with Bettas because of their need for high oxygen levels.
Some good betta tank mates are Ghost Shrimp, Dwarf Gourami, Corydoras Catfish, and Otocinclus Catfish. It is important to note that Bettas have been known to be fin nippers and may harm other fish in a tank.
Other fish that do not mix well with Bettas include large or aggressive fish (such as goldfish), other tropical fish, and non-bottom dwellers.
Breeding
If your tank is properly set up, with plenty of plants and hiding places, you can easily breed delta tail bettas.
A betta’s breeding season begins around the age of 14 months. Bettas that are less than two inches in length are not sexually mature.
If you wish to successfully spawn your betta fish, you will need a few females in your collection. A female betta can easily be distinguished from a male because her fins and tail do not flow, and her appearance is rather plain.
In close proximity to the floating plants you’ve provided, the male delta tail will build a nest of bubbles. The bettas then begin courting. The male drives the female under his nest, where he ’embraces’ her. The female then begins to lay eggs. Eggs are collected by the male delta tail and placed in the bubble nest. The male then guards the eggs until they hatch.
For the first few months, the fries feed on yolk sacs, hanging from the nest until they are strong enough to swim. Once the fries are strong enough to swim, you can start feeding them. Provide live food like microworms or specially formulated fry food from a fish store.
Are they aggressive or peaceful?
Delta tail betta fish originate from the betta species, more commonly known as Siamese Fighting fish, this means they are aggressive fish. Bettas come from parts of Asia, including Thailand, which was once known as Siam. Male bettas are known to be highly territorial and can be very aggressive toward other fish that invade their space.
Delta tail betta fish care
When it comes to betta fish care, there are a few key factors that affect your delta tail betta’s overall health and happiness. While most people think their new pet is happy in its small tank, in reality, a more spacious tank will give them more room to swim and bring out their best colors.
Also, essential to provide plenty of hiding spots such as live plants or silk plants so they have a place to rest during daylight hours. They also need clean water at all times and should be fed three times per day with high-quality food specifically made for bettas.
Finally, because these fish come from tropical climates, they prefer warm water temperatures around 75 degrees Fahrenheit. If you can’t keep up with these requirements, consider getting another type of aquarium pet like goldfish instead.
Delta tail betta fish diet
While adult betta fish are carnivores, they require live food to maintain a healthy diet. If you feed your fish sinking pellets or flakes that sink straight to the bottom of your tank, it’s likely he will ignore them and go hungry. Instead, use small live foods like bloodworms and brine shrimp to ensure your fish gets all of its nutritional needs met.
You can also purchase frozen foods at pet stores if you prefer not to deal with feeding live food. However, be sure these frozen foods don’t contain any preservatives; chemicals in preservative-filled frozen foods can harm your fish over time.
Lifespan
These fish species can live for 2-4 years.
Parasites and diseases
Unfortunately, delta tail betta fish are very susceptible to disease and parasites. Weekly water changes are critical for reducing your fish’s risk of sickness, as is good nutrition in the form of high-quality aquarium food. Parasites can be treated with medication that you can buy at pet stores or online; make sure you follow instructions carefully so you don’t end up making things worse.
Do delta tail betta fish make good pets?
The short answer is yes, as long as you have a little time to spare each day to take care of them. Delta tail betta fish can live upwards of 4 years, but they tend to be most happy and healthy when given at least half an hour per day of special attention.
