How cory catfish compatibility depends on tank size, group size, and bottom space.
Cory catfish can work with some bettas in larger tanks, but they need groups, clean substrate, and enough floor space. They are not suitable for tiny betta tanks.
Cory catfish are social bottom dwellers and should not be kept as a single cleaner fish.
They need room to forage and clean substrate that will not damage their barbels.
Some bettas ignore bottom fish; others harass anything in the tank.
