Hey guys so i got 4 black mollys a few days ago and noticed this on one of its head. It looks Silverish and didnt notice it before. Im running a 30 gal tank and my cycle is almost complete. It seems to be acting fine as well as my other 3 tetras.( once cycle is done im getting 3 more tetras) Ive use api quick start and ultimate water conditioner. Ill post a photo of my results i took just recently. I also did a water change today and plan to retest in 2 days. Am i looking into this too much?
