So I decided to turn my air stone off when I added my new oto cats to the 55 gallon tank until they were settled in.
Today I decided to turn it back on and came home to this. What is it? Has anyone else had anything like it? All my fish are still alive and active (thankfully)
I did previously have some Indian almond leaves in there but they never stained the sand before.
