I was looking at my aquarium and I found one of my balloon mollies hiding with stringy clear poop. I was instantly worried and have no clue what is going on. I tested my tank and realized my tank levels where high due to the fact I changed the gravel and have been doing between 10 to 30 percent water changes every other day. Of course I automatically did a 35 percent water change. Is there anything else I can do and is it just the water or something else. Also should I be doing more water changes or anything else to help the water. I have been testing everyday and making sure all of my fish are happy and all of them are but this guy. Any help is highly appreciated!
