Hello, everyone! My Betta fish died 3 days ago..I had him for almost 2 years and he died due to the dropsy syndrome . However, I really enjoyed having him like my baby. I'm looking forward to buy a new fish. But I'm not an expert about where should I buy him/her? And also I will like to have 2 fishes in the same aquarium. Which type of fish will you recommend me? Thank you!
