Male Siamese Betta Fighting Fish ~ 5cm


The Siamese Fighting fish is a complicated fish and should not be purchased on a whim. The name suggests that they are an aggressive species, but this is certainly not always the case.

Siamese fighters are hardy, full of character, and are peaceful to most other fish. They do not seem to enjoy open spaces, preferring densely planted areas of the tank. An ideal environment would be a small aquarium with a lot of plants and a few peaceful tank mates.             

We have specific colours listed on the website. If you buy a fighter from this listing then it will be picked at random. They are all beautiful and there are some great wierd and wonderful colours.

Species – Siamese Fighting Fish - Betta Splendens

Current Size – 4.5cm - 5cm

Adult Length – 7cm

Temperature Range – 24 - 28°C

pH Range – 6.0 – 8.0

Special Requirements - They are relatively easy to keep and are very hardy once settled, providing that they are not being bullied.

Tanks Mates and Compatibility – If you stock 2 male fighters together then all hell will break loose and you will end up with one battered fighter and the other one will probably be dead. They can also be aggressive to other long finned tank mates. However, usually, if housed with standard community fish, they pose no threat at all. In fact, they can be prone to having their beautiful fins nipped and this is often more of a problem. They can also be prone to stress if they are perpetually being nipped.

Feeding – They are not fussy eaters, accepting flakes and pellets along with live and frozen food.

We recommend:


Please note – Some images used are library photos and will show the colour potential at a fully mature size, as our fish are juveniles they may vary.

We always aim to supply the fish as close to the purchase size as possible. On rare occasions if this is not possible we will contact you.

The fish are selected at random however you are welcome to make a note on the order and the fish manager will do his best for you, requests are dependent on stock at the time of your order.

    Fantastic service as always. The fighter I received was the exact colour I requested, so I’m very happy. Fish itself is beautiful and seems happy/healthy.

    Fantastic service. Kept updated at every step and fish arrived in good health and settled quickly. Colours were a little faded at first but he quickly settled into his new home. Really happy with my betta and will definately be using Tropco again.
