Weird changes to mollie after holiday

[siverdollar]

Hi I have a balloon mollie in a small aqua one tank and went on holiday for a week with a feeder brick in the tank and now it has weird bubbles on its skin and top fin is fat and yuk. It still eats and swims well. :confused:

Water changes .Would say that feeder brick has rotten and given you amonia spike and burnt the fins then with poor water quality a secondry bacterial infection.do 30% water change add 1 teaspoon rock salt per 10l 5ml stressgaurd per 10l do this3-4 days in a row should clear it up.
