It's generally not recommended to mix guinea pigs of different ages and from different groups, as it can lead to territorial behavior and fighting. Introducing new guinea pigs should be done gradually and under supervision to ensure they get along well. It's best to have separate cages if you want to keep them together.
2 female Bettas can not produce young. I guess it is possible that two females could go through the mating processes but I have never known it to happen with Anabantids of any species.
Two Guinea Pigs are better.If you don't want babies,you should only buy two male or two female Guinea pig.
