Hey all,

Ive had these Swordtails for about a year now in my 75 gallon with some Firemouths and T. Aureus. Over the last month or two I’ve noticed some of the swordtails started getting what looked like loose scales and some smaller white patches for lack of a better term. I’m hoping it isn’t columnaris. They don’t seem to be acting any different and nothing has shown up on any of the cichlids in the tank or the pleco. Occasionally I can see a scale hanging off on one or two. Attached are a couple of pics (crappy ones) but best I could get since they move so damn fast.E2BBE2E2-495C-40F3-B1A6-A75F33A4D7A4.jpeg83A1D861-9873-4753-89B2-62E3F6D1BA71.jpeg
