New found hobby

Recently we started keeping fishes.. The reason why we started this new hobby is because we manage to 'scoop' one goldfish (actually mummy scopped many! Perhaps over 20 goldfishes but didnt realised that we can only bring one home...) during the summer event. But... The goldfish died 2 days later.. So we decided to buy new fishes since we have a tank.. Bought 3 killifishes!
