However, this condition does not always hold true as there is one tricky aspect that you will come across if you decide to breed your betta fish in an open community tank. Usually under this condition, your pet will adopt a totally different personality which will bring out their aggressive natural behavior to establish their own territory so that they can build their nest to care for their young. Attention also needs to be given, if let’s say when you try to mix two or more male betta fish into the same community tank because in this scenario, they will also try to draw a borderline with a territory to call their own and encroachment to each other’ den naturally means provocation and will result in a fight. However, this statement is only holds 50% true because under different conditions, I’ve seen before two or more male betta that can coexist with each other and main reason, why this is possible is because the tank is large enough to accommodate all of them and allow the fish to live far away apart from each other. Anyway, if you decide to try out, make sure that you are willing to spend more time and put on more effort to place close observations, because in the end you cannot predict or expect what will happen. Also if you decide to breed your pets, it would be worthwhile to move them to another tank because definitely, adding a breeding pair to a community tank is not a good idea at all.
Sometimes despite all the precautions taken without any breeding activity taking place with only one solitary fish added to the community, things can still go horribly wrong when your betta fish start to turn aggressive especially towards their smaller tank mates. If this happens, the only thing left to do is to take them out or just in case you don’t have the luxury of having additional aquarium, you can just use a tank separator or divider instead. In this scenario, you might be wondering and kept asking yourself on what went wrong that can induce the betta fish to act aggressively even though it is not in the breeding mood. Although there is no general consensus on what leads to this provocative nature, the most logical explanation is that the fish you are adding has already been subjected to solitary confinement, teased, or have been induced and prepared for fighting. What this means is that the fish has been kept in small bottles living under harsh condition or forcefully put on closeup view facing their potential fighting partner. Thus when the same fish that has been exposed to this undesirable condition are put into community aquariums, they will exhibit the same aggressive behavior and will lead them to attack their tank mates. For those young betta fish raised from small fry to reach adulthood and spending most of their time with their siblings, this type of betta will end up generally friendlier and is rather unlikely that they will turn hostile or hurt their tank partner. Well I think that is about all on this topic and hopefully the bits and pieces of information here and there will help to equip yourself and be more prepared should you decide to go ahead and mix your betta to your community aquarium. All in all, always remember, if things don’t turn out the way you intended, just take them out and remove them to another aquarium.
