Cleaned tank sides, bottom, and filter, big water change today, fish were fed at 10:00am and 3:30pm. Nitrite is still high but has not changed. Two weak fish today and one dead. The fish will not be fed over the weekend (tomorrow and the next day), as the librarian will be out of town, and I don't have a key. This will be their first weekend without feeding, so we'll see how this goes, they should be fine though.
