Siamese Fighting Fish - Betta Splendens

Betta fish are native to Asia, where they live in the shallow water of marshes, ponds, or slow-moving streams. Male bettas are devoted fathers who build bubble nests for their young with their mouths and fiercely protect their babies from predators. Male siamese fighters are a beautiful species, presenting in many different colours with real personality. Siamese fighting fish, like us, follow a day/night cycle, active during the day and sleep at night, requiring darkness to get a good night’s rest.

As the name suggests, male Betta fish are typically aggressive, especially towards other male Betta - so solitary aquariums, or tanks with bottom-feeder tankmates are recommended. Temperament can vary, so you can attempt to house them with other species, but please do your research prior. Male Betta's can be kept while breeding with female Siamese fighters, to be left alone to guard the eggs once the bubble nest is established.

Our range of Betta's are selective and individual, so unless stated the fish in the image is the one you will receive.

What can you keep with Betta Siamese Fighting Fish?
Despite being aggressive by nature, the temperament of male fighting fish can vary, and they can be kept quite happily with certain other species of fish. Other male Betta's, and gouami's, are a definite no. Siamese Fighter Fish must be kept with peaceful species, male Betta's are often housed quite nicely with catfish, snails, danios, corydoras, angelfish, tetras and less colourful guppies. If they all live together in a tank that features ample plants, you just might find success. Refrain from housing Siamese fighting fish with gourami's, barbs, characins or fin-nipping fish. If aggression becomes an issue in any community tank, you should keep and maintain a separate suitable quarantine aquarium in which individuals can be placed to avoid conflict.

Can you keep Siamese Fighter Fish in jars, pint glasses, vases or small pots?
The real question is, why would any responsible fishkeeper want to? Betta Fish, in certain parts of Asia, are culturally kept in jars or very small containers, in collections, or often for cruel sport purposes. Some supermarkets in the USA sell them on shop shelves in small pots, often with less than a litre in them, which really isn't cricket. While yes, Betta's have adapted to these habitats, it's really not ethical to keep them in anything smaller than a 15L aquarium, which is well-filtered, with plenty of environmental aspects to interact with (plants etc) that will not harm, stress or depress your fish.

Do Siamese Fighting Fish eat shrimp?
Yes, Betta fish do commonly eat shrimp. It is not a good idea to house them with small shrimp species, like cherry shrimp. Larger specimens such as the Bamboo Shrimp are too big to eat, and will cohabit quite nicely.

How do Siamese Fighter Fish Betta Splendens breed?
When betta fish breed, male bettas build a bubble nest at the surface and attract a female to it. Once a pair is formed, they perform a mating ritual. When the female begins to lay eggs, the male retrieves them and deposits them in the nest, where he will protect them until hatched. Females must be removed once eggs are laid.

Ease of care
Moderate - aggressive, so be selective with tankmates or keep solitary. Betta's will appreciate leaves, or broad leafed plants such as anubias, and will often sleep on them.

Compatibility
Aggressive typically, do not house with other male Betta's. Choose tankmates with care - do your research and choose only peaceful, docile tankmates, avoiding long-finned or fin-nipping fish.

Diet
Feed tropical fish flake or small granules, supplement occassionally with daphnia, brineshrimp and other frozen meaty food. Take care not to over-feed, as Betta habitats are often small/nano aquaria and are easily polluted by remainder food.

Breeding

Male Betta's will produce a bubble-nest on the surface to spawn with females, wherein she lays her eggs. Remove the female once the eggs are fertilised, males will protect them until hatched.

Life Span
The typical lifespan of a Siamese Fighter Betta Fish is 3-5 years in perfect conditions.

ALL SEASON IS TOO WARM!
Size: King, Style: All-Season
I got the King, All Season, to squeeze into a Queen duvet for extra floof and it's sooo cozy. Highly recommend. I redacted 1 star though because although it says All Season, the amount of down in here feels like it's for winter. The first night I used it I woke up dripping in sweat. It's currently March, I live in Los Angeles area, hitting about 75° weather outside rn, but I sleep with AC full blast at night (usually hit about 64 when I wake up). I can't sleep with it, I'll need to buy the "cool" one, and hope that isn't tooo thin. Don't get me wrong, it's a great insert, but holy hell, it's too heckin' warm. I saw someone else mention it and wish I had honed in on their comment. I don't wanna return it as it was used, so I'm stuck with it now. *UPDATE* I am back because I also bought the "Cool" blanket as well after experiencing the heat of the all season and it too is also too hot for me. I've had a duvet before but I guess not filled to the capacity of these blankets. If you're a hot sleeper maybe look elsewhere?

Buy this instead of the ‘brand name’ one
Size: Twin, Style: Warm
Tl:DR: Buy it, it’s super cheap, better than the one I paid 2x the price for and soft as it can get, and it really is a ‘Winter comforter’. This review is going to sound like I got paid off for it but I actually didn’t. I bought another comforter prior to this one, paid close to double of this one and that the ‘on sale’ price, and it is trash compared to this Amazon basics one. Both claim to be thick warm comforters but I can literally stack two of the other brand and maybe they’d be almost as thick as the Amazon one. I only bought this one because the other ‘winter’ one I bought was so thin and flimsy I figured adding another ‘cheapie’ one might make me not freeze to death. As soon as I arrived I noticed that this Amazon one was WAY thicker, nicer looking, softer and warmer than the old one. Just to try it out I stacked both of them together to see if I wouldn't freeze to death like I was doing with the old ‘expensive’ one: five minutes in and I was sweating. That’s all it took, I immediately removed the duvet cover from the old one, switched it to the Amazon one and threw the old one somewhere where I couldn’t see the money I had wasted, and yes the Amazon was warmer and softer even WITHOUT the duvet cover. I’m probably going to get the light version for when fall hits and I don’t quite need the heavy one yet. Buy it you won’t regret it and hey it’s Amazon brand so if you don’t like it they’ll take care of you, but I HIGHLY doubt you won’t love this thing.

Great duvet insert
Size: King, Style: Light
Perfect duvet insert. I got a pretty expensive duvet to cover this and they worked great together. The fit was perfect and I didn’t feel like the duvet was smaller than its cover. This was a cheap option that keep us warm while not being too think. This product is also breathable and recommend if you live in a place that transitions from hot to cold often.

Great mid-weight comforter

Great comforter, especially for the price. I put it in the dryer for a bit when I first got it and it became nice and fluffy. Perfect mid-weight duvet.

Hotel quality, budget friendly
Size: King, Style: Light
I’ve only used this for several nights. Overall I’m pretty happy with it, especially for the price. It is soft to the touch and has a nice, smooth feel. It’s lightweight but still provides enough warmth for mild to cool nights. I don’t like feeling weighed down when I sleep, so the light fill is actually a big plus for me. If you’re someone who sleeps hot, this is a solid choice. The corner tabs are super helpful. I paired it with a duvet cover and haven’t had issues with shifting or bunching. It also fits my bed well, though I could see it being a bit short on the sides if you have a very thick mattress. This is a great budget-friendly option and seems like it will be easy to maintain.
