In panaji, it is far more profitable fishing in a lake than doing work online, especially advertising and content writing.
For example on 6 June 2019, the domain investor, personally observed some boys fishing in the lake in campal,panaji, goa with very basic fishing equipment like nylon wire, and fishing hook
Within 10 minutes they had caught 3-4 big tilapia fish.
The fish were fairly large more than 20 cm in length
According to the boys fishing, 3 fish are sold for Rs 200 in the panaji market
So clearly if a person is only interested in making money, working online is a big waste of time, fishing in the lake or river will be more profitable.
Goldfish are popular pet fish because they can be trained like other pets. For example when the pet owner will enter the room, the gold fish in the bowl are immediately detecting that the pet owner has come to the room, and are frantically asking for food . This is in contrast to other types of fish like Koi, Fighter Betta Fish which are largely passive and do not react when there is any movement or noise in the room where the fish bowl is located
The goldfish are also easy to keep fish as they as they remain alive for a relatively long period of time without much maintenance or care, in contrast to other fish like Koi, Guppies which are dying quite quickly
So though expensive at Rs 150 a pair, gold fish are highly recommended as pet fish
