First: You have way too many fish in your tank. This stresses out your fish and kills them.

Second: Everyone is going to ask you this, what are your ammonia, nitrIte, and nitrAte levels and is your tank cycled? (How long have you had your tank? When did you put fish in?)

Third: I don't think you want to change the sponge filter white mat thing because that's where your beneficial bacteria live. (Right?)

The water parameters will be the first step in determining what is wrong with your fish. Also what is your water change schedule and how much each time. What kind of filter do you have?
