Betta fish are widely known as fighting fish. Frequently sold in individual containers, you might believe all Betta fish have the same general appearance and demeanor. Regardless of what you see at pet stores, male and female Betta fish are quite different. Subtle differences in their appearance and behavior can help you differentiate their sex. Knowing the sex of a Betta fish is critical when deciding if and when to breed a pair of Betta fish.
Does My Male Siamese Fighting Fish Get Lonely? - Pets
The bettas we know today have long flowing fins and come in all sorts of striking colors, due to genetic mutations while breeding. Their long flowing fins is a distinguishing characteristic that is only acquired by the male, female bettas are generally smaller and have short fins. Male betta's aggressiveness is another trait that sets them apart from female bettas. Male bettas are much more aggressive than female bettas, that is why male bettas cannot be kept together where they are in contact with each other. Once in contact, they will instinctively fight to the death, hence the name siamese fighting fish. It is very important that the owner understands to respect this animal's trait, rather than to use it as a form of entertainment.
Siamese Fighting Fish: Betta - Male.
Male Siamese fighting fish, also known as bettas, have a reputation for being angry looking and antisocial. The lonesome fish don’t mind a lack of company, and they’re usually content swimming blissfully around their tank. But a few select species of fish and couple of toys can spice things up in a betta’s dull life.
Why do male and female betta fish fight in the same tank? - Quora
But these two statements all depend on the fish and its personality that's why it can be a shoot or miss which is what its like with all bettas and most fish, but not all "fighter" fish are nasty and i hate the reputation these fish have! But females can be kept together i think in 3s or 4s. I had my female and male together and they got on fine my female submited to him and they went on but my male is a wimp and gets bullied by everything so he has a nice 20G. Also a male and a female should only be together (if they do fight) when breeding time comes which is when i THINK the female shows stripes but some have striped bodies anyway like mine and when the male makes bubble nests but theres a whole lot more too it. Hope you house the male! If you have not already try get some caves and densly planted areas but it is strange your female doing that as females are more peacfull, it could be stressed due to ammonia etc though?Two female bettas may tolerate each other, provided they have sufficient hiding places. Try having them loose together in the large tank, but keep a close eye on their behavior. Some individuals are feistier than others and may never cope with having free access to another betta, although they’ll probably be fine with other fish species. If they carry on fighting, add a partition.
