I bought 9 neon tetras from a local fish store yesterday. Noticed one fish has a strange pale patch on only one side. Concerned this could be neon tetra disease. I’ve moved the affected fish into a solo 7 gallon quarantine tank for now with heater and filter media from the main tank. They are eating and swimming normally as far as I can tell. The other 8 all seem normal and have no discolouration other than not having brightened up fully as of yet. Any help is appreciated!
