Abstract In Southeast Asia, males of the Siamese fighting fish Betta splendens have been selected across centuries for paired-staged fights. Background Artificial selection and experimental evolution are powerful tools for testing proximate and ultimate causes of behaviour. Methods Study species We compared the behaviour of a wild-type and a fighter strain of B. Full size image. Table 1 Description of the aggressive behaviours quantified. An aggression score was calculated as the average frequency of these displays Full size table.
Results An overall analysis of the results shows that fighters had an aggression score three times higher than wild-types Table 2 , Fig. Table 2 Three-way ANOVA results with factors sex male and female , strain fighter and wild-type and treatment conspecific, mirror and control and interaction between the factors.
For the aggression score, only two levels of the factor treatment conspecific and mirror were included as aggressive behaviours were absent during control trials. Discussion Domestication is a type of experimental evolution usually associated with intentional selective breeding and where control over the selection process is low [ 1 ]. Example of tanks used for staged pair-fights in fighting rings across Southeast Asia.
Conclusions The study highlights that long-term selection for male winners of staged fights ongoing in Southeast Asia with B. Availability of data and materials All data is available upon request from the corresponding author.

MD Angels. Good points by SK. I was also going to say that plakats and giants are more aggressive, BUT, it otherwise is really dependant on the individual betta. Soo buying a blood fighter on aquabid won't be a super friendly fish?! Okay was just looking at half moon crowntails and normal bettas at my lfs so I guess it will just depend on the individual. It really is. But as a "general rule" bettas don't get along well with other fish. Not to say that it isn't impossible, because there are people on here that have bettas in community tanks, and have no problems tank size, tank mates, hiding places, etc.
I have had viel tails be super aggressive, and some that were very laid back. I have 2 half moons now, and one seems more aggressive than the other the little one, of course and then I also have a crown tail that seems pretty aggressive. I have never personally kept males in a community tank, but I have kept females with no problems. I find the more aggressive ones are the ones that really react to you more. You can wave at them from across the room and they will get excited and "dance".
Are you planning on putting the betta in a community tank, or will it be solitary? Click to expand It's not going in a community it will be going into a 5 gallon with maybe 2 African dwarf frogs or just a apple snail. A 5 gallon isn't enough for 2 frogs and a betta. Bio-load wise, 5 gallon is absolute minimum for 2 ADF's alone. From experience the nitrates can rise quickly. Apple snails create a lot of waste. Too much for a 5 gallon imo. A good rule, don't buy bettas on AB labled "fighters" or marked with a star system.
Of course this is if you don't want to support betta fighting. If you could care less then buy as you see fit. In a community aquarium, bettas will attack other brightly colored or flamboyant fish, but get along better with plainer, less colorful species. Adult bettas grow to inches long, not including the length of their fancy, flowing fins.
Males have far more elaborate fins than females, and captive bettas have been bred to produce fins in a wide variety of shapes. Wild bettas have smaller fins and are generally dull, camouflaged shades of gray, brown or green, but captive bettas can be found in a rainbow of colors, including turquoise, orange, red, green, blue, gold, purple, yellow and copper, or combinations of those colors.
Bettas can breathe air or get oxygen through their gills, making them a good fish for less active tanks. Betta fish fighting instincts will also be at higher levels after males have built their bubble nests. They are living at higher aggression levels during this time and will respond more aggressively than normal. Healthy fish also make the best Siamese Fighting Fish. Establishing healthy and stable water conditions should come before you train your Betta fish to fight.
This includes a well-filtered water column as well as proper ph and temperature levels. Smaller fish tanks increase their territory in space provided and will make them more active also.
Reasonable fight club conditions can also be created by competing fish of similar age and size. Smaller Betta fish will retreat more readily from larger Bettas. As you train your Betta fish to fight, just remember that they are naturally aggressive and perform best when they are in good shape.
As their name implies, Siamese Fighting Fish Betta fish are highly territorial, making them naturally aggressive. Food and mating are major factors for their aggressiveness, which can be directed at females as well as other fish species. Providing plenty of space and hiding places, as well as carefully selecting tank mates will reduce fighting. Of course, aggressive behavior can be increased with conditioning and training, as these are intelligent fish.
