I just want to clarify this for future people reading it, or if youre still thinking about it.
Having bred bettas 1/2 liters are too small, and bettas are full grown or nearly full grown at 3-3 1/2 months of age. If you would look on aquabid you will find people all sell theirs at 3 months full grown. Please rethink breeding them
