Okay I saw something strange this morning. I have a sally lightfoot crab that has been in my 75g for about 6 months, no problems. This morning I am looking and I see sally on top of a rock. She is covered in hair algae......on her pinchers and a bit on her back. The strange thing is, I don't have any hair algae anywhere that I can see in my whole tank......soooo where did this come from? She looks funny, all hairy and alll......the strange things I see.....
