i have a new 275 litre aqarium which has been running about 3 weeks. after a week i bought 6 marble mollies and within days some started to develop red and swollen mouths which eventually caused the death of 3 of them . i went to the people who supplied my tank and they tested the water and they advised i change 25% of the water every day for a week.which i did but now i notice that one more of my remaining 3 has started to develop the same thing.can anyone please advise where im going wrong?
