Did you dechlorinate the water before adding the fish? Also that seems like a lot of fish for a 10 gallon. I would suggest getting a test kit to check the quality of the water. I recommend the API freshwater master test kit. You can buy it at most pet stores or order it on amazon. It is possible that you had a huge ammonia spike from adding so many fish into a small, unestablished tank. If your ammonia or nitrites are above normal (honestly above 0.25 ppm
) than you need to start doing water changes until they get under control. Ammonia and nitrites are deadly to fish. You could also use seachem prime to help detoxify the ammonia and nitrites for like 24 hrs, but it is not a replacement for water changes. Also, do you have a heater and an air stone?
