I purchased 3 Mollys that were in my big 55 gallon tank, within days one Molly started getting a white puffy looking spot on it's head so I put them in a 10 gallon quarentine tank, the spot went away and I just figured it was an injury. They were in there for about a month when she gave birth and so I moved them all back in the big tank and left the little tank for the babies. WELL NOW..... She's looking weird again! Now she's getting like a cloudy/fuzzy spot on her back fin and one of her side fins. I don't get it! The only difference between the tanks that I can see is that the ph of the little tank is usually between 7.2-7.4 and the big tank will never rise above 6.6. But the other Mollys are fine so I don't really think the ph is causing this, could it? I tried to get some pics but it's hard to see in them. Here ya go, hope the pics work. Also, when I moved them to the quarentine tank after I bought them I added some salt to it. My big tank doesn't have salt. Can I add salt with my irredessent sharks? I heard it's bad for scaleless fish.
