While I was in the hospital my fish tank light was left on. I came home to what I thought were dead crypts but my tank is covered in diatoms from a solid 4 days of light. I was planning on adding my shoaling fish next but now I'm thinking seriously about the otos. From my understanding they are the only fish that will actually eat diatoms. I just want to know how much truth there is to this. Thanks!
