In Goa it is becoming extremely difficult to get proper fish food, sometimes it is being stolen also. Only granule type fish food is available which is not suitable for smaller fish like guppies. So till fish food is easily available, it is better to focus on growing plants for which less resources are required
It is observed that the price of fish greatly varies from store to store. In some stores, they are keeping the price of the fish almost the same for a year or more, in other stores, the price of the fish varies weekly depending on the stock of fish available.
Most of the smaller fish sellers are keeping the price of their fish like goldfish, tetras, clownfish, angel fish almost the same at Rs 50 a pair. However larger pet stores, which are mainly selling dog food, are charging more money and their prices will vary.
For example a month ago, the price of platys at a store was Rs 50 a pair, and now the prices of the platys increased to Rs 80 a pair. So it is advisable to purchase the fish when they are cheap
