Betta Sorority Tank Plans

[SQW]

I would be curious to see the paper on the color thing! I haven’t found it yet, apparently. Can you link it to me? (Also, have not found color to affect aggression levels in any of my sororities

I heard this a while ago on an aquarium forum, I don't think if this is true. I also heard that female bettas are less aggressive towards siblings. I don't know if any of this is true.

Ah, I see. This is the only paper I am aware of regarding this topic, and it does not address aggression levels at all. It found that females, when given the choice between swimming with a group and swimming along, or swimming with a single individual, the females would choose to swim with the group. And when given the choice between swimming with a group of the same color as the individual, or a group of different colored fish, it would choose to swim with the group that was the same color as itself. So they prefer larger groups, and they prefer the same color. However, a final test they did, was the choice between a group of a different color, and an individual of the same color, and they did not find a significant preference regarding this, but they did spend more time with fish of the same color over the larger group of a different color.
I am not aware of any papers addressing aggression between females based on colors, but there is always new stuff being published! So there may be something I am not aware of

yes, same color /fin type = less aggression

I just added a young juvenile to my 38 community which has 6 adult bettas about 10 days ago

2 adults are same color fin type, no issues

my elephant ears bettas are same way, they will swim side by side no aggression.

I have had sororities that were all same color(s), and also sororities where not a single fish was the same color. No aggression issues in either.

I would argue individual temperament and introduction methods play a larger role in aggression than color/tail type.

My sorority is a very interesting bunch, and I really only have one betta who is aggressive. The others are very chill. It really depends on the bettas you find. All of mine are just your normal pet store bettas. But, they do have ember tetra tankmates.
