Well the little guy did too good of a job. I left for a week to go out of town on some training and the sea hare is not looking good right now. There is very little hair algae in the tank now but he doesn't seem motivated to find any food anymore. I pulled him out of the tank worrying that he might die and crash my tank. The last two nights he has been buring himself under sand. Does anyone know where I can find some Nori? I check a Walmart as someone recommended but couldn't find any. I live in dtown Cleveland. If I can't find any soon I will be looking for anyone who might be willing to give him a temp. home.
