When Fishes are your Pet
We are habituate to see fish in market. In market, they are purchased as food. We also see them in pond or large pond or river, sea too. But, when they are swimming in aquarium water, they are the pet.
Petting Fish is not a bad habit. They brings a natural beauty in your home or office also. you may become the owner of the petted fish. So easy.
Only one time a day, they need to serving food. In a month, the aquarium should be cleaned.
That is the job.
