This summer I'm planning to setup a betta sorority tank. What suggestions and experiences do you guys have to help me so I can setup a good home for the bettas. There is going to be 3 cory cats in there with them fyi.
You need at least a 20 gallon for 3-5 bettas (odd numbers for some reason work best) and there needs to be at least 6 corydoras. I'd say a thirty gallon for them all would be best, maybe a school of nano fish that aren't super active.
- the tank needs to be heavily planted so that the fish can get away from each other. A few plants should reach all the way to the top
- corydoras need to be temperature compatible
- be prepared that you might need to remove a fish. Have a backup plan.
