Hi everyone. I'm not sure what is going on with my ACF. She had a small white spot on her a couple of weeks ago and now there are a couple of them. I was away for the week and just got back from vacation so the spots are very noticeable now. Any idea what they are and what to do about them? I noticed her activity level is down a little bit from where it was a few weeks ago.
Just to give a little background, she is about 4 years old now and lives with two other ACF in a 55 gallon aquarium with 4 blue gouramis. They've never had any issues getting along so they've always been together. I am also having a separate issue with algae growing on the sand a few weeks after cleaning the tank. I only run the lights about 5 hours ago and it still happens. My only thought is maybe the LEDs are too strong and allowing the algae to grow. Thanks to anyone with suggestions. I tested the water and the nitrate and nitrite seem to be in normal range.
